Abstract

Solid state rechargeable polymer electrolyte batteries utilizing lithium anodes and V 6O 13 composite cathodes were investigated at 100°C. The polymer electrolyte was a complex formed between polyethylene oxide (PEO) and LiCF 3SO 3. Over a hundred cycles were obtained at the C/5 rate (45% depth of discharge) with greater than 75% of the initial capacity of V 6O 13 being maintained at cycle number one hundred. Cells made with propylene carbonate (PC) doped polymer electrolyte also showed good performance at room temperature.
