✦ Synopsis

The characteristics of an Li/LiV30s polymer electrolyte battery have been examined by charge-discharge cycling tests and by frequency response analysis. The results indicate that cell failures, such as capacity decline upon cycling, are a consequence of geometric inadequacy, probably resulting from electrolyte flow, positive electrode modifications, and lithium dendrite formations.

Improvements in the electrode structure and optimizations in cell design are required to assure high cycling performance of the polymer electrolyte battery.

Experimental

The PEO-based polymer electrolytes were prepared by casting. The procedures included the dissolution of the two components in purified acetonitrile, the mixing of the solutions, and the slow evaporation of the *Author to whom correspondence should be addressed.
