ELECTROLYTE COMPOSITION FOR ELECTRIC DOUBLE-LAYER CAPACITOR, SOLID POLYMER ELECTROLYTE, COMPOSITION FOR POLARIZABLE ELECTRODE, POLARIZABLE ELECTRODE, AND ELECTRIC DOUBLE-LAYER CAPACITOR

摘要

An electrolyte composition and a solid polymer electrolyte for electrical double-layer capacitors are endowed with high ionic conductivity. The invention is also directed at a polar electrode composition and a polar electrode having excellent binder capabilities which are able to strongly bond a high surface area material such as activated carbon and an electrically conductive material to a current collector, and which also have shape stability. A high-performance electrical double-layer capacitor arrived at using the above compositions and components is additionally disclosed.
