Iljin was the first in Korea to develop and produce Elecfoil needed for PCB (Printed Circuit Board) production. As the first company to accomplish this feat, Iljin is now the world leader in top-quality Elecfoil production operating the world’s largest factory.

A printed circuit board is an electronics component in which Elecfoil attached and etched on an insulated polymer constitutes a microcircuit that mounts active and passive elements.

Elecfoil is a thin copper foil that makes up these PCBs. It is produced by melting copper wire that is extracted from CuSO4 and made to order for clients. It is a core component in almost all electronic products such as televisions, computers, and cellular phones.

In line with the rapidly changing IT industry, Iljin Materials focused on the multi-functioning and smaller design of electronics products, and developed a high value- added high-functioning special Elecfoil early on to become the world’s second largest Elecfoil producer.

Elecfoil is also used for cathode collectors in rechargeable lithium batteries for almost all cellular IT products such as cellular phones, laptop computers, digital cameras, and camcorders.

With the rapid growth of cellular IT products, electric vehicles, functional robots, and the environment-friendly energy industry, we expect the rechargeable lithium battery market to take-off. Especially in the case of Elecfoil, it has already surpassed the small batteries and has expanded into larger product areas such automobiles and energy storage.

I2B, the Elecfoil for rechargeable lithium batteries produced by Iljin Materials, currently has the world’s top market share, and Iljin invested more than 100 billion won in expansion efforts to meet the ever increasing demand thus creating a launch pad for a second take-off.

We will contribute to Korea’s industry securing world-class technological competitiveness by maximizing synergy with the Energy Business Division to produce high capacity, high output rechargeable lithium batteries to meet market needs.

LED CHIP

BUSINESS AREAS

From cellular phones, displays, and lighting to Automobiles, LED will brighten the future with Environment-friendly lights

The application of LEDs is so diverse that it is said to be

a new revolution within the optical technology industry.

Iljin Material’s LED Business Division will produce the best LED chip

to become one of the world’s top 3 LED producers;

in turn becoming a new growth engine for Iljin Group.

Products - InGaN LED Chip

LED (Light Emitting Diode) is an electro-optic semiconductor device that junctions p-type semiconductors to n-type semiconductors whose majority carriers are electrons and holes, respectively. As electricity is applied on the device, it uses the characteristics of the compound semiconductor to produce light at the desired wavelength efficiently.

LEDs have high light-conversion efficiency, so they have very low energy consumption. Also as a small light source, LEDs make it possible to make things smaller, flatter, and lighter. They do not discharge mercury or gases, and are semi-durable making them environmentally-friendly.

With global warming threatening the environment, the LED industry is at the center of low carbon emitting green energy growth. LEDs, mainly used in lighting have a longer lifespan than incandescent light and are energy efficient. Therefore, it is gaining attention as an alternative light source that reduces carbon emission.

Starting in 2012, many countries will phase out the use of incandescent lights followed by fluorescent lights. By 2015, it is expected that LEDs will take up 30% of all lighting. The effects of this expansion will not only affect the LED industry but all industries.

The application of LEDs is so diverse that it is said to be a small revolution within the optical technology industry. LEDs are used not only as lighting but also as the flash in cellular phones, the Back Light Unit (BLU) in flat screen televisions, in cars, and agriculture. Therefore, the average global LED market size annual growth rate is expected to be 20%.

Iljin Materials launched our LED Business Division in 2011 with the completion of our Ansan plant, and we are focusing on research and development to produce the best LED chip. From sapphire wafers produced by Iljin’s Display Business Division, to LED packages produced by Iljin Semiconductors and module lighting produced by Lumirich, Iljin Materials was the first in the world to complete vertical integration of LED production.

The current size of the lighting market in Korea is an impressive 10 trillion won with potential to grow. The LED Business Division will use our outstanding technological know-how to become one of the world’s top 3 LED producers; in turn becoming a new growth engine for Iljin Materials.

THE ENERGY BUSINESS DIVISION PROMISES A BETTER FUTURE WITH EXPERTISE IN ENERGY TECHNOLOGY

BUSINESS AREAS

By producing core rechargeable Lithium batter y materials, we will provide Solutions for growing energ y needs

Iljin Material’s Energy Business Division’s LMO (LiMn2O4) is getting a lot of attention

in the rechargeable lithium battery market for its safety and cost-competitiveness.

Therefore, the Energy Business Division plans to create synergy with Elecfoil for

anode current collectors to expand and grow in the energy storage

industry with electric vehicles, solar energy, and wind energy.”

Products - LMO (Lithium Manganese Oxide)

The Energy Business Division, which produces the cathode active materials in

rechargeable lithium batteries, began 2010 filled with optimism. Rechargeable

lithium batteries are semi-durable in that they may be charged and reused.

Rechargeable battery production technology is a core technology of the future along

with solar and wind energy to protect the environment and decrease energy use.

The cathode is the positive end of rechargeable lithium batteries and takes up the

largest portion of the component at 30-40% of the battery itself. Therefore, it is a

high value-added product.

There are five different types of cathodes which are separated depending on the use

of the rechargeable lithium battery. LCO, LNO and NCM have high discharge capac-

ity and high density. Therefore, they are used in small IT product batteries. LMO and

LFP have outstanding safety so they are used in high power application and mid- to

large-sized rechargeable lithium batteries.

Iljin Energy Business Division’s LMO (LiMn2O4) is especially getting a lot of attention

in the rechargeable lithium battery market, due to its higher rate capability, safety,

and cost effectiveness than LCO, LNO, and NCM which have dominated the high

capacity portable rechargeable battery market.

Until 2009, the main demand for LMO was for rechargeable lithium batteries in

electric power tools, and LMO produced by dry process met these demands.

However, the HEV market prefers the LMO with a more uniform particle shape which

can be produced by wet process. Therefore, the LMO market for HEV will focus on

suppliers who have the technology to produce high density LMO by wet process.

The Energy Business Division will produce next generation high-voltage electrode

materials, 300mAh/g or higher electrode materials, and new products in order to

solidify its position as the leader in the electrode material area.

LIGHT SOURCE FOR ELECTRONICS DISPLAYS

An environment-friendly light source,

it does not have any heavy metals and

needs low electric power.

Therefore, it is expected to be used in

more products in the future. Currently

it is used in lighting buildings, special

lighting, portable lighting, automobile

headlights, electric fields, street lights,

landscape lighting, fishing lamps, and

lighting on farms. Iljin Materials’ prod-

ucts has a high efficacy rate at high op-

erating current making it an ideal light

source.

LIGHT SOURCE FOR LIGHTING APPLICATIONS

IHT (HIGHLY FLEXIBLE LOW PROFILE ELECFOIL FOR FPCB)

I2K (HIGH CAPACITY, HIGH OUTPUT ELECFOIL FOR ANODE CURRENT COLLECTOR IN RECHARGEABLE BATTERIES)

IUT is an ultrathin Elecfoil especially de-

signed for PCBs used in computer CPUs

and other complex memory devices that

are high density, high integration, high

layering and have microcircuits. IUT is

used in semiconductor packaging (Flip

Chip, CSP) and High Density Intercon-

nect (HDI) circuit boards. Since its thick-

ness is less than 3㎛, it is attached to a

carrier Elecfoil thicker than 18㎛ to make

handling easier.

IUT (ULTRATHIN ELECFOIL WITHCARRIERS)

A specialized low profile, high strength

Elecfoil used on circuit boards in semi-

conductor packaging,t is thin but is able

to withstand thermal fatigue. IKD is avail-

able in 9, 12, and 18㎛.

IKD (LOW PROFILE & HIG STREN-GTH ELECFOIL FOR PACKAGING SUBSTRATE)

As a main component in Printed Circuit

Board (PCB) and Copper Clad Laminate

(CCL) production, ICS is a general pur-

pose Elecfoil. It is used in a majority of

the electronic products we use today

such as televisions, refrigerators, washing

machines, and computers. It is available

in 12, 18, 35, 70, and 105㎛ thickness.

ICS (ELECFOIL FOR PCB)

INS is a next generation of general use

Elecfoil. It has a lower and more even sur-

face to enhance adhesion to the resin. It

is possible to use in environment-friendly

halogen-free circuit boards.

R&D Results & Current Status

Striving to create a better future, Iljin today is the result of bold R&D investments

RESEARCH & DEVELOPMENT

The first in Korea to develop Elecfoil, copper clad steel cable, fittings for distribution, industrial

diamonds, the world’s first single panel LCD for projectors, and five wavelength white LED….

Bold technology development is Iljin Group’s fundamental mindset.

In 1968 when Korea depended solely on importing high value-added products, Iljin

focused on developing these products in order to overcome Korea’s struggling economy,

which at the time did not have a strong profit structure. Since then, Iljin has led Korea’s

materials industry.

Iljin successfully overcame the entry to market barriers and was one of the first companies in Korea

to donate a joint research institute to Seoul National University, thus giving back to society.

Iljin Materials began joint research efforts with Seoul National University in 1978, and by 1987, was

able to begin mass production of Elecfoil for PCBs. In the decades since then, Iljin Materials con-

ducted more than 20,000 experiments and made bold investments to become the world’s leading

companies with proprietary technology development in Elecfoil.

In addition, Iljin Materials expanded its business into the areas of LED and electrode materials for

Li-ion battery by continuing its efforts in R&D.

The key in Elecfoil manufacturing technology lies in making it thin and even. The thickness is in units of micrometers (㎛) or 1/1000 of 1 mm. Elecfoil thickness generally ranges from 12㎛~70㎛, but with the demand of IT products that need thinner Elecfoil, Iljin developed Ultra Thin Elecfoil with a thickness of 1㎛, 3㎛, and 5㎛.

Iljin Materials was the world’s second manufacturer to successfully commercialize Elecfoil for rechargeable lithium ion batteries demonstrating its global technological strength, and its own Elecfoil was selected as a “World Class Product” by Korea’s Ministry of Knowledge Economy.

Iljin Materials’ Technology Research Institute was established in 1991 and is composed of four institutes. They focus on Elecfoil technology and develop components and materials industry seed items for new business possibilities.

Iljin Materials will continue to strengthen our technological competitiveness and guide future businesses. By establishing our own research system, we will strive to create a new R&D model to venture into new areas.

Major Patent Status

Conducting more than 20,000 experiments in the past few decades, Iljin Materials continues to lead the world with proprietary technology development in Elecfoil.

Iljin Materials develops more than 90% of its production in-house, and reinvests more than 10% of revenues into research and development.

To meet the demand of thinner lighter IT products, Iljin developed Ultra Thin Elecfoil with a thickness of 1㎛, 3㎛, and 5㎛.
