ION CONDUCTOR

摘要

Disclosed is an ion conductor having high ionic conductivity even around room temperature, low viscosity, incombustibility and excellent oxidation resistance. This ion conductor satisfies the characteristics required for polymer electrolytes of lithium secondary batteries, capacitors and solar cells. Specifically disclosed is a polymer ion conductor containing a polymer ion-conductive compound (I) and an electrolyte salt (II), wherein the polymer ion-conductive compound (I) is composed of an amorphous fluorine-containing polyether compound having a fluoroether group in a side chain or a crosslinked product thereof.
