This invention relates to a cathode composite for use in a primary battery and a secondary battery. In order to uniformly disperse a positive active material and a conductive agent in the cathode composite, wherein the cathode composite comprises a polar organic molecule, a chalcogen containing positive active compound, a conductive agent and a diluent, wherein the polar organic molecule has at least one acid structure based on phosphoric acid, sulfonic acid, boric acid, carboxylic acid or sulfuric acid and functions as a dispersant.

Cathode composite

A galvanic cell is in which at least one of the negative electrode, the positive electrode and the separator comprises a solid electrolyte prepared by doping an ionic compound to an organic polymer. The organic polymer is a polymer obtained by crosslinking an organic compound having a structure of the general formula (I):

A primary invention is a solid polymer electrolyte including an ionic salt and a compound able to dissolve the ionic salt and having a crosslink network structure. A crosslink network structure is formed by polymerizing a two-functional acryloyl compound having two acryloyl groups with a one-functional acryloyl compound having one acryloyl group. In this solid polymer electrolyte, the crosslink network structure has a skeleton in which the one-functional acryloyl compound spreads into branches. Since molecular movement of this branched skeleton is active, its flexibility is improved.
