Characteristics of lithium iron batteries: 1. High weight energy density: — 100Wh/kg, much better than lead acid ~40Wh/kg 2. High rate capability — Up to 30C for surge, 3~5C for continuous use 3. 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 7 Performance of Supreme Ferrous Cathode Material (SFCM ) Capacity Test conditions: 4.4 • Three electrode test cell 4.2 • C/10 charge/discharge • Lithium reference Voltage (V) 4 • 14~16mg/cm2 3.8 3.6 3.4 3.2 3 2.8 0 50 100 Capacity (mAh/g) 8 150 Features of SFCM 1. 2. 3. 4. High in materials consistency 130±3 mAh/g Excellent in high rate capability: continuous >10C durable High in solid content: 55wt% or more High in active material (>95wt%): - No additional carbon black needed, - Binder less than 5 wt% 5. High in rolling density: Normally > 2.2g/cm3 6. Excellent slurry characteristics: Free flowing at high solid content (55 wt%) 7. Production efficient: - Allows fast coater speed owing to less solvent content - Excellent adherence to the substrate (No further treatment for substrates required ) - Water based binder/solvent system allowed -- As a result, high yield, high performance batteries can be obtained at low cost ! 9 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) 10 Current Status of SFCM • Materials patent has been applied worldwide including US and Japan • Supreme Ferrous Cathode Material (SFCM) — Current Production 480 Tons / Year • A New plant will deliver 4800 Tons / Year in 2009 (World #1 Manufacturer and Supplier) 11 Example I.

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 tests with 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 27 Contact Window • Formosa Energy & Material Technology Co., Ltd. • Sales Manager Steven Chen : [email protected] TEL : (886) 2 2712-2211 ext 7819 FAX : (886) 2 2717-8381 28 28
