Why Lithium Iron Why Lithium Iron System?System?
Characteristics of lithium iron batteries:1. High weight energy density:
— 100Wh/kg, much better than lead acid ~40Wh/kg2. High rate capability
— Up to 30C for surge, 3~5C for continuous use3. Cyclability
— Minimum 2000 cycles with 70% capacity remaining— Potential to 5000 cycles
4. Safety consideration— The best in lithium iron batteries, compatible with lead acids
5. Environmental consideration— No toxic component and is RoHS compatible — Waste reduction eventually owing to prolonged cycle life
6. Price consideration— Expected to be comparable with lead acids
7. Availability— Materials required are the most abundant elements in the world

Conventional LiFePO4 Formosa’s SFCM
1
General formula: LiFePO4 General formula: Li Fe(1-x)MxP(1-x)O2(2-x)
This material does not obey the LiFePO4
stoichiometry (proved by chemical analysis as (Fe+M): P ≠1:1)
2 Olivine structure Defective olivine structure plus the allowance of impurities
3 No creation of defective structure Creation of defective structure by means of oxidizing atmosphere as well as the incorporation of “stoichiometric compounds”. This is totally different from any prior art starting with the stoichiometric ratio of Li: M: P = 1:1:1 (Simple cation substitution)
4 Defect type: None Defect type: Anion defects
5 Structure and property relationship not clear (Structure--- > not necessary excellent property; Structure --- > not easy processing protocols or high processing difficulties such as inert atmosphere)
Structure and property relationship is obvious (Defective structure --- > good electronic conductivity --- > not sensitive to carbon content --- > as a result, low processing requirements)

ConclusionsConclusions• SFCM based batteries will replace lead-acid, nickel cadmium,
nickel metal hydride batteries, and become the main stream of high power, large scale power batteries
• Formosa has the production capability of 480 tons/year (currently the world #1 materials provider). The new plant will extend the production to 4800 tons/year in 2009
• Formosa has been successful in the development of heavy duty or high power systems for applications such as UPC, vehicle starting, fork lift, E-motorcycle. All applications shown have been either commercialized or in the process of field testswith potential customers
• The concept of “localized” and “miniaturized” energy saving system should be promoted and advocated in the future for resolving the energy and environment problems simultaneously
