Why Lithium Iron System?
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, 35C 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

Features of SFCM

• High in materials consistency 1303 mAh/g
• Excellent in high rate capability continuous
  gt10C durable
• 3. High in solid content 55wt or more
• 4. High in active material (gt95wt)
• - No additional carbon black needed,
• - Binder less than 5 wt
• 5. High in rolling density Normally gt 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 !

Conclusions

• 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 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
