The Overcharge and Overdischarge Behavior of Polymer Electrolyte Cells.

Abstract

The overcharge and overdischarge behavior of the cell Li/(PEO)8 LiCF3SO3/V6O13 is being investigated with particular emphasis on the changes taking place at the cathode. Cells placed on overcharge have shown an inability to discharge. Optical microscopy has revealed severe electrolyte and cathode degradation with the presence of white fluffy deposits located at the cathode-electrolyte interface. This was shown by EDAX analysis to be predominantly rich in salt. Vanadium was also detected at the Li-electrolyte interface.
