Low-cost, lightweight rechargeable lithium ion batteries

The performance of a low cost, prismatic Li-ion rechargeable battery technology based on the LiMn 2O 4/C cell chemistry is described and compared to a cylindrical LiCoO 2/C cell. The LiMn 2O 4/C cell has demonstrated constant current charge, discharge and pulse discharge rate capability comparable t...

Description
Summary:The performance of a low cost, prismatic Li-ion rechargeable battery technology based on the LiMn 2O 4/C cell chemistry is described and compared to a cylindrical LiCoO 2/C cell. The LiMn 2O 4/C cell has demonstrated constant current charge, discharge and pulse discharge rate capability comparable to the more expensive LiCoO 2/C technology. For simulated high power radio operation, the high power LiMn 2O 4/C cell offers performance comparable to the commercial LiCoO 2/C cell. The cycle life demonstrated to date of the LiMn 2O 4/C cell, while adequate for military application, is shorter than the LiCoO 2/C cell.
