I am sorry I did send a wrong information in a former message viewtopic.php?p=8480#p8480
saying i-miev battery might be a Lithium iron phosphate battery
Here is the Material Safety Data Sheet of the LEV50 50Ah 3.7V Lithium Ion Cell

：Lithium-Manganese Dioxide (activity)
Polyvinyldiene Fluoride (binder)
Polyvinyldiene Fluoride (binder)Electrolyte
：Organic Solvent (non aqueous liquid)
：Heavy metals such as Mercury. Lead, and Chromium are not used in the cell.
cell going into the i MiEV pack is a 50 Ah, 3.7V cell using a mixed LMO/NMC cathode
material with a hard carbon anode
. The combination offers a specific energy of 109 Wh kg-1, and energy density of 218 Wh L-1." http://www.greencarcongress.com/2009/06 ... 90612.htmlThe Battery Pack for Mitsubishi’s i MiEVhttp://www.greencarcongress.com/2008/05 ... ts/page/2/
Mitsubishi and GS Yuasa developed the cell for both high specific energy and high rate discharge. The newly developed prismatic cell used in the i MiEV pack has a specific energy of 109 Wh/kg and specific power of 550 W/kg. Energy density is 218 Wh/L. The entire pack has a specific energy of 80 Wh/kg.
The cell—and pack—feature high capacity retention at constant current discharges. Capacity at the high current of 200A is slightly less than at the lower rates (93.9% of capacity).
When discharged with an ambient temperature of 25° C, the pack is capable of delivering the maximum power from 80% DOD. Even at 0°C, the pack can deliver the maximum power from 70% DOD and enough power for propulsion from 90% DOD. http://bioage.typepad.com/.shared/image ... imiev2.pnghttp://bioage.typepad.com/.shared/image ... imiev3.pnghttp://bioage.typepad.com/.shared/image ... imiev1.png
