Abstract: 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.

Abstract: 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):Z-[(A).sub.m -(E).sub.p -Y].sub.k (I)where Z is a residue of a compound containing at least one active hydrogen; A is represented by the following formula (II) ##STR1## wherein n is an integer of 0 to 25 and R is an alkyl having 1 to 20 carbon atoms, alkenyl, aryl or alkylaryl; E is at least one of --(R.sup.2 O)--, R.sup.2 being an alkylene having two or more carbon atoms; Y is an active hydrogen or a polymerizable functional group; k is an integer of 1 to 12; m is an integer of 1 to 250; p is an integer of 1 to 450; and A is copolymerized with E. When E is --(CH.sub.2 CH.sub.2 O)--, A and E are random-copolymerized, but when E comprises --(R.sub.2 O)-- in which R.sup.

Abstract: This invention relates to a cathode composite for use in a primary battery and a secondary battery. In order to disperse uniformly a positive active material and a conductive agent in the cathode composite, the cathode composite is characterized by that it includes a compound having a pyridine ring in its molecular structure which will become a polar molecule, and functioning as a dispersant.

Abstract: At least one of the negative electrode, the positive electrode and the separator in the galvanic cell 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):Z-[E-Y].sub.k (I)where Z is a residue of a compound containing at least one active hydrogen, Y is an active hydrogen or a polymerizable functional group, E is expressed by --(A).sub.m -- or a block-copolymeric type group of the above A and --(CH.sub.2 --CH--O)-- in which the total sum of A is m and the total sum of --(CH.sub.2 --CH--O)-- is p, m is an integer of 1 to 250, p is an integer of 1 to 450, k is an integer of 1 to 12, and A is a group represented by the general formula (II): ##STR1## where n is an integer of 1 to 25 and R is an alkyl group having 1 to 20 carbon atoms, an alkenyl group, an aryl group or an alkylaryl group.

Abstract: 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.
