STATUS OF THE DEVELOPMENT OF RECHARGEABLE LITHIUM CELLS

[摘要] The progress in the development of the ambient temperature lithium-titanium disulfide rechargeable cell under development at the Jet Propulsion Laboratory is described in this paper. Originally aimed at achieving a specific energy of 100 Wh/kg, 'AA' cells have demonstrated 125 Wh/kg at the C/3 discharge rate. The results of evaluating cell design parameters are discussed and cycling test data are also included in the paper. Safety-tests results at various overcharge and overdischarge conditions and rates proved to be uneventful. The test results of cell with built-in overcharge mechanism proved the concept was feasible. Replacing the lithium foil electrode with a LixC resulted in a capacity at 1 mA/cm(2) of 200 mAh/g and 235 mAh/g at 0.167 mA.
