Performance of polymer-electrolyte cells at +25 to +100 C. Technical report

Technical Report ·
OSTI ID:6960722
;
Solid-state rechargeable polymer-electrolyte batteries utilizing lithium anodes and V/sub 6/0/sub 13/ composite cathodes were investigated at 100 C. The polymer electrolyte was a complex formed between polyethylene oxide (PEO) and LiCF/sub 3/SO/sub 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/sub 6/0/sub 13/ being maintained at cycle number one-hundred. Cells made with propylene carbonate (PC)-doped polymer electrolyte also showed good performance at room temperature.
