SOLID ELECTROLYTE COMPOSITION, SOLID ELECTROLYTE FILM AND LITHIUM SECONDARY BATTERY

摘要

Disclosed is a solid electrolyte composition containing a polyether polymer having a crosslinkable group, an electrolyte salt compound, and a compound represented by the formula (1) and/or (2) below as a photopolymerization initiator. This solid electrolyte composition has excellent film formability, sufficient mechanical strength and high ion conductivity, and is effectively prevented from deterioration in characteristics due to repeated charges and discharges (cycle deterioration).
