✦ Synopsis

An all-solid-state battery utilizing a thin, composite polypyrrolepolyethylene oxide positive electrode, solid polymeric electrolyte, and a lithium negative electrode was constructed and its cycling behaviour evaluated. Hundreds of cycles were reached before the coulombic capacity decreased to 60% of its original value. The gravimetric energy density of the composite electrode was estimated to be 55 W h kg-'. The disadvantage of the battery is poor charge retention, and high-rate performance is limited by the diffusion of anions in the polypyrrole particles.
