Poly(methylmethacrylate) (PMMA)- and poly(acrylonitrile) (PAN)-based g
el electrolytes were applied to Li/polypyrrole (PPy) battery and its p
erformance was investigated, These batteries showed excellent performa
nce with 3 V output voltage and 90-100% coulombic efficiency. Using ch
emically more stable PMMA gel electrolyte, long charge/discharge cycle
life more than 8000 cycles at 0.1 mA cm was obtained. (C) 1997 Elsevi
