Design and performance of 10 Wh rechargeable lithium batteries

New metal-carbon composite anodes were developed by a chemical deposition method of metal particles onto graphite powder, Silver-graphite composites consisted of ultrafine silver particles on a graphite surface, exhibiting a large specific volume capacity of 468-505 Ah/1 which may be due to Li Ag alloy formation, The Ag-graphite anodes also showed excellent cycleability over 700 charge/discharge cycles with only 3% capacity loss, 10 Wh class rechargeable lithium batteries with energy densities of 270-300 Wh/1 were manufactured using Ag-graphite anodes and cathodes of LiNiO2, or LiCoO2.,, Little capacity loss in these batteries was found even after 250 cycles because of the highly durable Ag-graphite anodes, (C) 1997 Elsevier Science S.A.
