Abstract: | Lithium-ion (Li-ion) batteries have demonstrated the ability to fulfill the energy storage needs of many new technologies. The most significant drawbacks of currently available technologies, such as LiCoO 2 based Li-ion cells, is their high cost and significant environmental hazards. Li-ion cells which use a lithium manganese oxide (LiMn2O4) spinel based cathode material should be much less costly and safer than LiCoO2 based cells. Performance data from prismatic design cells which use a LiMn2O4 based cathode material is presented and shown to meet many military performance criteria. The most significant drawback of this technology is the short cycle life |
