Our success story
RENATA – The Swiss Power Source
RENATA SA, with its head office in Itingen near Basel (Switzerland), is a worldwide leading producer and supplier of button cells for electronic applications. The business – founded in 1952 with the goal to produce mechanical parts for wristwatches – specialised in button cells in the late 70s.
Today, in the modern production plant at Itingen, all services (research and development, production,quality assurance and marketing) are grouped.
RENATA production plants in Switzerland and China are highly automated and produce over one million batteries a day. This includes silver oxide batteries for wrist watches, 3V lithium button cells for industrial applications (automotive, medical, telecommunications, and more). RENATA also supplies silver oxide, rechargeable lithium-ion polymer, zinc air batteries, as well as battery holders and power modules.
RENATA products are supplied according to its high standards and manages the whole production process: from punched battery housings, over the injection molded synthetic seal and the sourcing of the battery components up to the final assembly. Through this high production depth RENATA earned itself a reputation as an extremely flexible and reliable supplier of batteries.
The consistent high quality and power of the button cells is not lastly a result of the reliable quality assurance system of RENATA. This includes the complete production process – from the inspection of incoming raw materials right through to the testing of the finished product. RENATA is ISO9001 and ISO14001 certified. ISO14001 focuses on controlling environmental aspects and the way that activities, products, and services interact with the environment.

Chemistry and Construction
Chemistry of RENATA Li/MnO2 cells Renata CR lithium coin cells use a non-aqueous,aprotic organic electrolyte containing lithium per-chlorate in a mixture of organic solvents. The pro-prietary formulation of the active cathode materialconsists of a heat-treated mixture of electrolyticMnO2 and other specific components, yielding anoutstanding volume/capacity ratio for this Li/MnO2
system.
The cell reactions for this electrochemical systemare:
Anode: Li –> Li+ + e-
Cathode: MnIVO2 + Li+ + e- –> MnIIIO2 (Li+)
Overall cell reaction: Li + MnIVO2 –> MnIIIO2 (Li+)
Manganese dioxide is reduced from thetetravalent to the trivalent state by lithium.
The separator system in Renata coin cells isespecially designed to ensure the bestperformance in terms of mechanical strength, ionpermeability over a wide temperature range (-40 to +100°C) and a low self-discharge rate.Additional care in cell design also minimizes self-discharge rate.
The combination of these several featuresprovides the best performance for long lifeapplications (back-up etc.)

Electrical & Temp. Performance
Pulse discharge characteristicsRENATA Lithium batteries have excellent pulseload characteristics, for example for thetransmission of radio signals by remote controls.The following diagrams show the voltagecharacteristics at pulse loads of 10, 20, and
50 mA during 100 ms, pulse cycle 1 second, atambient temperature. The voltage drop under loadis evident as well as the voltage recovery toalmost the original level after a very short time.
Please contact Renata for further details.
Inverse currentLithium primary batteries are not rechargeable.Therefore, if there is a possibility of electriccurrent flowing from the main power source to thebattery, the circuit must include two suitableblocking diodes in series or one blocking diodeand one protective resistor in series (refer to drawing in chapter SAFETY GUIDELINES) Use asilicium diode of small inverse current to preventcharging. The total amount of recharge energydue to leakage by the blocking diodes should notexceed 1% of the battery's nominal capacityduring its total service life. A higher input of re-charge energy may harm the battery or reduce itsperformance.
Example: A CR2450N battery with a nominalcapacity of 540 mAh is expected to supply powerfor 5 years. The amount of tolerable re-charge
energy is 5.4 mAh, corresponding to an inversecurrent of 0.123 µA for the total service life1).Consequently, a blocking diode with an inversecurrent not greater than 0.1 µA should beselected. Please note that the inverse current ofblocking diodes varies with temperature.
Short circuitsWhen lithium batteries are short-circuited, it takestime for the battery voltage to recover, even incase of slight short-circuits. If electrical characte-ristics are measured while the battery is recover-ing, the battery may appear to be defective, but isnot. Short-circuiting leads to deterioration of thecell capacity. Short-circuiting of batteries musttherefore be avoided, except for wave or dip soldering. Use an instrument with a high inputimpedance (minimum 10 M�) for measuringopen circuit voltage.

Frequently Asked Questions (FAQ)
Which values of open circuit voltage dolithium cells typically show?The CR-type coin cells, based on the lithium/manganese dioxide electrochemical system, havea nominal voltage of 3 V. In practice, a freshlithium cell will typically show an OCV (OpenCircuit Voltage) between 3.10-3.40 V. This rangeof values is intended for measurementsperformed at room temperature; in fact, the OCVvalues depend on the temperature of themeasurement.
After storage periods the cells may also showvalues outside this range, due to ageing effects(see the recommended storage conditions forlithium coin cells, also reported in this document).
What is the internal resistance of a cell?How does it affect the performance of thecell?From an electrical point of view, a cell is acombination of an energy source and aresistance. The internal resistance (Ri) is a keyparameter for a cell, as it determines its high-power capability (i.e. its ability of delivering itsenergy in a short time). The internal resistancereduces the useful voltage in applications andleads to internal heat, thus loss of energy, whichincreases with the square of the current.
The internal resistance of lithium cell is a sum ofboth ohmic contributions and of resistivecontributions coming from electrochemicalphenomena taking place during the discharge ofthe cell. By accurate selection and quality control
of materials, Renata manufacturing processminimizes the resistive factors contributing to theinternal resistance of the lithium cells.
As the internal resistance includes a number ofresistive contributions coming from electro -chemical phenomena, each of them beingcharacterised by a time constant, the value ofinternal resistance is pretty much depending fromthe measuring method and conditions. A simpleand inexpensive method for measuring the Ri is toapply a resistive load (R1) to the cell and tomeasure the value of the cell voltage under load(CCV, Closed Circuit Voltage). The internalresistance is then calculated as:
Ri = ( OCV - CCV ) x R1 / CCV.
Does the internal resistance changes withtime, or during the cell discharge?Generally speaking, there is a limited, physiolo -gical increase of the internal resistance of aprimary cell during its service-life. In the case oflithium coin cells, the normal increase during thecell discharge is due both to ohmic factors (thedistance between the electrodes increases duringdischarge) and to electrochemical phenomenataking place at the lithium anode (growing ofinterface films between lithium metal andelectrolyte solution).
The increase of the overall internal resistance withincreasing discharge level is reported in the figurebelow.

General electrical performance
Frequently Asked Questions (FAQ)
The ageing of the cells at normal conditions (i.e.room temperature, max. 40% of relative humidity)will also lead to other physiological increases ofthe internal resistance, due to normal ageingphenomena taking place at the electrodes.Though of limited extent, these types of increasesof the internal resistance are normally to beexpected and must be also taken into account,when designing a new application.
Exposing the cells to elevated temperatures, then,can lead to further grow of the passivation films atthe anode, with an additional increase of internalresistance. Furthermore, increasing thetemperature above 70°C can cause the internalresistance to abnormally increase (because ofelectrolyte leakages and degradationphenomena). Abuse conditions such as dischargeat elevated currents and short-circuit can alsoincrease the internal resistance abnormally,because of the deterioration of cell internalcomponents.
Which is the voltage drop of the lithiumcell during current pulse? The voltage drop during a current pulse (�V) isthe difference between the cell voltage just beforeapplying the pulse (Voltage-high, V1) and the cellvoltage during the pulse (Voltage-low, V2):
�V = V2 - V1
It is also expressed by the formula:
�V = Ri x Ipeak,
where Ri (internal resistance) depends on the celltype and dimensions. In addition, the value of Ridepends on the temperature and on the dischargelevel of the cell (see related section about internalresistance). Therefore the voltage drop of the cellwill be strongly affected by the temperature andby the cell's discharge level.
From the above reported formula it also followsthat the voltage drop strictly depends on theapplied pulse itself-particularly on the value of thepulse-current (Ipeak). The voltage drop is alsoaffected by the other parameters that define apulse-load: the pulse duration (i.e. how long thepulse current Ipeak is applied), the pulse period(i.e. the time between two subsequent pulses), thefrequency with which the pulse trains occur (i.e. how often the pulse trains are applied to thebattery) and -eventually- the basis-current (i.e. thecurrent applied between two pulse trains). Thelast three pulse parameters affect the voltagedrop during pulse, because their settings affectthe value of the cell voltage just before applyingthe pulse ( V1 ).
An example of voltage and internal resistancebehaviour during a pulse discharge is reportedbelow (Figure 2).

Frequently Asked Questions (FAQ)
What is the maximum pulse current thelithium coin cells can handle?There are no specified limits for the peak currentvalue in pulse applications. Instead, current limitscan be defined by means of a series of factorsand practical considerations related to theelectrical application, like the load profile, the cut-off voltage and the targeted service-life of thecell in the application. Electrical applications arenormally regulated by a voltage threshold (cut-offvoltage), under which the applications miss therequired electric energy to work and therefore willshut-down. The cell is the energy/voltage sourcein the application; when the voltage during apulse is lower than the cut-off voltage, theapplication will shut down. A proper design of theelectrical application in terms of electrical loadand cut-off voltage, combined with the choice of
the cell of right energy and power characteristics,are of paramount importance in order to achievethe targeted service-life of the application. Themutual relation that links application characteris -tics, cell performances and targeted applicationservices is graphically illustrated below.
Consult Renata experts in order to calculate andselect the cell with the right characteristics foryour application and achieve your goal!
What is the shortest time period fortesting the behaviour of batteries?
It is common to perform accelerated tests toprove the lifetime of the battery in the applicationor to test the performance of different batteries.According to IEC 60086-1 it is recommended todischarge the battery for a period of approx. 30 days. With the standard discharge currentgiven on page 7 of this Designer's Guide oneachieves 100% of the nominal capacity withinthese 30 days.
However, also expedited test are possible whenthe resulting capacity decrease is taken intoconsideration. The limit of the average dischargecurrent is the max. continuous discharge currentgiven and explained on page 7. It is notrecommended to perform tests with currentsbeyond this limit because the results may not betypical or they could be misleading. Li/MnO2
batteries are designed to supply low currents forseveral years. Therefore, test results are ratherrandom when discharging the batteries in veryshort time periods with high currents.

Influence of temperature on electrical performance
Frequently Asked Questions (FAQ)
The operating temperatures of lithium coin cellsare given on page 7. Below –30°C the pulsecurrent performance of the cells is significantlyreduced, due to the increased internal resistance.
Ambient temperatures over the given max.operating temperature may be possible for a shortperiod of time. Please ask Renata experts foradvice on this matter.
Has high temperature any detrimentaleffect on the cell performance? Increasing temperature to values above roomtemperature will increase the rate of self-discharge, reducing the available cell capacity –thus shortening both the service-life and theshelf-life. The self-discharge of a cell is due toparasitic reactions taking place at the electrodes,consuming the electroactive material. As for everyreaction, the rate of these processes is function oftemperature. A simple "rule of thumb" todetermine the self-discharge at a giventemperature is the following: the rate of self-discharge increases of a factor 2 for every 10degrees Celsius of temperature increase fromroom temperature (20°C). Given that at roomtemperature the rate of self-discharge of lithiumcoin cells is 1% of capacity loss per year, at 40°C(for example) the self-discharge rate will be:
1% x 2(40-20)/10 = 1% x 22 = 4% of capacityloss/year.
In addition to self-discharge considerations, themaximum storing and operating temperature forthe lithium coin cells must not exceed the givenmax. operating temperature, in order to avoid anyelectrolyte leakages, leading to reductions of cellfunctionality.

Has low temperature any detrimentaleffect on the cell performance? Generally speaking, the performances of a cell atlow temperature are reduced because of thedecreased conductivity of the electrolyte, whichleads to an increase of internal resistance. As a
consequence, the ability of the cell to deliver highpower is reduced. Especially when designing anapplication with high power demand (high currentconsumption, like pulse-loads), this factor must becarefully taken into account.

Influence of storage / ageing on electrical performance
Influence of contact material
Frequently Asked Questions (FAQ)
Which are the recommended storage conditions for lithium coin cells?The normal storage of lithium coin cells is madeat temperature between +10°C and +25°C,never exceeding +30°C (also according to IEC 60086-1). In this way the maximum shelf-life (i.e. max. retention of cell performances afterstorage periods) of lithium coin cells is achieved.Storage temperatures above room temperaturewill increase the rate of self-discharge, reducing
the available capacity of the cell. Humidity above95% R.H. and below 40% R.H. should also beavoided for sustained periods, as these extremesare detrimental to batteries.
Storing the cells at low temperature is alsosuggested, but attention must be paid whentransferring the cells to warmer environments,because of the possibility of having watercondensing on to the cells (risk of short-circuits).
Which contact materials are recommen-ded?Recommended contact materials:• Gold plating – provides the most reliable metalto metal contact under all environmental conditions.
• Solid nickel – provides excellent resistance toenvironmental corrosion.
• Nickel-clad stainless steel – performs almost aswell as solid nickel.
• Nickel plated stainless steel – also a reliablemetal to metal contact (also used for RENATA'sbattery holders SMTU/HU series).
• Inconel alloy – provides good electrical conduc-tivity and corrosion resistance.
Never use tin plated contacts since in highhumidity and polluted environments sulfides canform on the material and creep through pores inthe coating.
Which contact force and design ensurebest electrical performance and reliability?The contact force of the contacts should bebetween 2 and 10N (ca. 200 to 1000 gf).
Contact design: It is important that contacts applysufficient pressure to hold the battery firmly inplace and prevent electrical disconnections (evenunder shock conditions). Contacts must be able toresist permanent set. Furthermore, two contactpoints guarantee more reliability than only one.
Can batteries undergo washing proces-ses?Please use non-conductive cleaning solutions forthe PCB washing process. In conductive solutions,the batteries are short-circuited, causingdischarge, voltage drop and possibly deteriorationof the cell performance. Use cleaning solutionsthat do not attack the polypropylene cell gasket.
Are Renata lithium cells certified in termsof safety?The safety of Renata cells is certified byUnderwriters Laboratories Inc., Northbrook/IL/USA, under the file number MH14002. Seealso: www.renata.com/content/3vlithium/tech_safety.php and the Safety Section in this Guide.
General FAQs
Passivation Phenomena
Lithium is among the most reactive elements. Iteasily reacts with a number of substances,including water and air. Because of this highreactivity, the commercial exploitation of lithium-based electrochemical systems has been for longtime hindered by the reaction between lithium andseveral electrolytes. Only in the 80s suitableelectrolytes were developed, based on aproticorganic solvents which are stable when in contactwith lithium metal.
The reason for the stability of electrolytes basedon organic solvents lies in the passivation layerthat is built at the lithium surface.
This protective layer (also called SEI, Solid-Electrolyte-Interphase) stops the reaction betweenelectrolyte and lithium and due to its mechanicalcharacteristics also ensures good stability for longtimes. Therefore the formation of a layer of rightproperties is a key element for the achievement oflong-term storage properties.
The formation of the SEI layer is influenced by anumber of factors, including the formulation of theelectrolyte and the production conditions. Inaddition, a particular step of the manufacturingprocess plays a decisive role in the formation ofthe right SEI layer: the pre-discharge step (i.e. a
discharge limited to some % of the theoreticalcapacity of the cell) of 100% of the producedcells. By carefully controlling the pre-dischargeparameters, a passivation layer of optimizedphysical-chemical characteristics is created at theinterphase lithium-electrolyte.
Unlike other lithium-based battery technologies,the CR (Li/MnO2) system is not characterised by apassivation layer of growing thickness after long-term ageing of the cells or after short exposuresat high temperature. The SEI layer of CR cells builtat the beginning does not change significantlyeven after years of storage at controlledtemperature (see related section in this chapter –FAQ about recommended storage conditions). Inother lithium systems, instead, a growth of thelayer with ageing time, is observed, turning out ina reduced pulse capability (the well-known"voltage delay effect, especially observed forliquid cathode systems when trying to requesthigh pulses after long time storage at roomtemperature, or after short periods at hightemperature). For these other lithium systems it isnecessary to apply a continuous load of lowcurrent to minimize passivation phenomena; onthe contrary, for CR systems this precaution is notnecessary.

Soldering
Hand solderingNever solder directly to the cell surface. Use cellswith tabs only (see related section of our ProductsLine). Do not allow the soldering iron to getdirectly in contact with the battery body. Do notapply heat any longer than necessary to achieve asafe solder connection (max. 350°C for 5s in the soldering area of the tab).
Wave solderingDuring passage of the battery terminals throughthe solder wave, the battery is short-circuited. Asthis usually takes less than 5 seconds, the loss ofcapacity is negligible. Subsequent to a short-circuit the battery voltage will recover to a valueabove 2.5 V almost immediately. Full recovery tothe initial voltage may take hours or even days.Please note this effect in case electricalcharacteristics are measured while the batteryvoltage is recovering. The battery may appear tobe defective, but it is not. Temperature at thebattery needs to be controlled below 85°C.
No reflow soldering with batteriesNever use reflow soldering on batteries! Lithiumbatteries are not suitable for reflow solderingprocesses. The high temperatures required forthis soldering method would deform the gasket,causing electrolyte leakage, deterioration of thebattery performance and possible rupture orignition.
Reflow soldering of SMTU holdersIf assembly by reflow soldering is requested, it ispossible is to solder a Renata battery holder of theSMTU series but place the battery into the holderafter the soldering process. The peak temperatureof the reflow soldering profile is recommended tonot be above 270°C for 40 s (245°C for another40 s).

Abnormal Charging TestThe cells were charged by being connected inopposition with a 12 V dc power supply. Thecurrent was controlled by connecting a resistor ofthe appropriate size in series with the cell. Thetest duration was based on the applied currentand the capacity oft he cells.
The cells were examined after these tests for anysign of change.
Five samples each of Models 1000-0, 1000-7and CR2450N in the as-received condition wereused in these tests.
None of the cells leaked. There wereno fires or explosions as a result of tests atcurrents below 100 mA for the abnormal chargingmode.
Results
Crush TestsThe cells were crushed between a flat surfaceand a cylindrical surface having a radius ofcurvature of 5/16 in. The force was applied bymeans of a hydraulic ram and the cells werecrushed until the thickness at the point ofmaximum crushing was less than one-fourth ofthe original cell thickness. The temperatures onthe exterior surface of the metal cell casing wasmonitored by means of an iron-constantanthermo-couple. The cells were examined after the
test for any signs of reaction due to the crushing.Five fresh Model CR916 cells were used in thistest.
The casings opened and leaked as aresult of this test. There was no temperatureincrease or any other adverse reaction as a resultof this test.

Disposal of used batteries
Safety Guidelines
General GuidelinesThe disposal of used batteries is governed by lawin many countries world-wide. Therefore, pleasecheck your local regulations prior to batterydisposal.
Safety Precautions for disposal of usedbatteries. Safety precautions for the handling andstorage of used lithium batteries.Although environmentally friendly and free ofharmful substances, lithium batteries are apowerful energy source and require some cautioneven if almost fully discharged. When disposing oflarge quantities of lithium coin cells it is necessaryto take certain safety measures in order to avoidheat generation and the danger of fire due tomass short-circuiting:
1. The number of lithium coin cells to beingdisposed of and placed in the same containerduring a day should be limited (if possible lessthan 100 pieces per day).
2. The container for disposal should be madeof metal (small steel drums are quite suitable), not
exceed a volume of 10 liters, be closed with acover and have air holes in the upper area of theside walls.
3. For the storage of these containers, the follo-wing safety rules should be observed:
• Containers to be stored outdoors, protectedfrom rain, at least 2 - 3 meters away from buil-dings.
• Distance between containers at least 1 meter.• Storage area not accessible to unauthorizedpersons.
4. It is recommended to mix the batteries in thecontainers daily for one week in order to ensurecomplete discharge and prevent the battery wastefrom heating up at a later stage.
As indicated above, these safety measures areonly necessary if relatively large quantities oflithium batteries must be disposed of at the sametime. In the retail/consumer trade, where onlysingle batteries are changed and used batteries ofdifferent kinds are mixed together, there is no riskof battery waste heating up dangerously.
Quality Management System
Since the very beginning of its business activities,when Renata first started as a supplier ofbatteries to the Swiss watch industry, it developeda high level of quality-consciousness. «Qualitycomes first» rules at every level of the enterprise.
Renata's quality management system is certified according to the ISO 9001 and ISO 14001 standard.
The basis for providing our worldwide customerswith top quality products is our continuousproduct and process improvement.
The open circuit voltage (OCV), closed circuitvoltage (CCV) and mechanical dimensions of everysingle RENATA lithium battery are checkedindividually.
Batteries only leave our factory after a mandatorystorage period (quarantine) of at least 3 weeks.During this period of time extensive performancetesting is done.
This testing comprises:
• various leakage resistance tests• shelf life tests• storage under varying atmospheric conditions(artificial aging)
• discharge tests to monitor capacities• electrical characteristic testing (voltage, internalresistance, etc.)
• visual checks, including internal components ofdismantled batteries
The flow chart on next page shows the mainproduction steps and the integrated quality controlprocedures for RENATA lithium batteries.
The controls on the product are the following (seeprocess flow chart on the next page):
Statistical control ("Quality tests" step)performed for every batch, consisting of a) discharge capacity checkb) leakage tests
After the Quality tests are successfullycompleted, 100% of each batch is controlledin terms of OCV, internal resistance (resistiveload method) and height ("Final control100%" step).
If the battery is tabbed, after the tab welding100% of each batch is re-controlled in termsof OCV, internal resistance (resistive loadmethod; "Battery tagging 100% electricaland tags" step).
