POLYMERIC ELECTROLYTE VARNISH, AND POLYMERIC ELECTROLYTE, COMPOSITE ELECTRODE, POLYMERIC ELECTROLYTE ELEMENT OR ELECTROCHEMICAL DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polymeric electrolyte varnish and a polymeric electrolyte with high productivity without discharging an organic solvent so as not to have adverse effect on work environment, a composite electrode with low interface resistance, a polymeric electrolyte element and the composite electrode with high productivity and excellent film thickness uniformity without discharging the organic solvent so as not to have adverse effect on work environment, and an electrochemical device with excellent adhesive property between the polymeric electrolyte and the electrode. SOLUTION: This polymeric electrolyte varnish comprises (A) a polymeric solution synthesized in an electrolyte solvent and (B) electrolytic salt. The polymeric electrolyte is formed by cross-linking the polymeric electrolyte varnish. The composite electrode is formed by cross-linking the polymeric electrolyte varnish on a negative electrode material or a positive electrode material. The polymeric electrolyte element is formed by applying and cross-linking the polymeric electrolyte varnish on a support body. The composite electrode is formed by laminating the polymeric electrolyte element on the negative electrode material or the positive electrode material so that the polymeric electrolyte side comes in close contact. The electrochemical device has the polymeric electrolyte.
