Abstract
A solid electrolyte comprises a microporous film having high crystallizability and excellent solvent resistance. The microporous film is controlled by a wet phase inversion method to a porosity of 50% or greater and a pore diameter of 0.02 μm to 1 μm inclusive. The solid electrolyte may be used to construct an electrochemical device, a lithium ion secondary battery and an electric double-layer capacitor.
