Lithium battery

リチウム電池

Abstract

PROBLEM TO BE SOLVED: To provide a battery having excellent discharging performance and the excellent changing and discharging cycle performance by arranging polylinyl pyridine layer, which contains the electrolyte, on the surface of active material grains, and filling a clearance between the grains with solid electrolyte or gel electrolyte so as to manufacture an electrode. SOLUTION: In a lithium battery having a negative electrode made of the material, which can store and discharge lithium, an electrode is formed by adding the electrolyte solution of polyvinyl pyridine to the active material for kneading so as to form a polyvinyl pyridine layer on the surface of the active material grains, and thereafter, adding the high molecular solid electrolyte or the gel electrolyte for kneading, and coating it on a collector. With this structure, a clearance between the grains is filled with the high molecular solid electrolyte or the gel electrolyte so as to form a solid electrode. The polyvinyl pyridine layer has the excellent wettability in relation to the grains and the high binding performance. Since an electrode can be formed by only mixing the active material grains and the solution of polyvinyl pyridine, drying of the solvent is unnecessary. COPYRIGHT: (C)1997,JPO
