Title:
MANUFACTURE OF ALKALINE STORAGE BATTERY AND ITS ELECTRODE
Document Type and Number:
Japanese Patent JP3460509
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve charge/discharge characteristic using a base board formed by integrating a conductive core material which is composed of a porous material such as a metal board or a net with nickel fibers constituted of a core part, which is raised from the both surfaces of the core material and composed of carbon fibers, and a nickel layer covering its surface.
SOLUTION: After a polyvinyl butyral-based adhesive has been applied on the both sides of a nickel plated steel punching metal 1 of numerical aperture 42%, rayon fibers are transplanted and the surfaces of the punching metal 1 and the rayon fibers are coated with nickel with a prescribed thickness. The rayon fibers are heated in a non-oxidizing atmosphere, so as to be formed into carbon fibers, the nickel applied on the punching metal 1 and rayon fiber surfaces, and the core material are burned, and the obtained base board is filled with an active material. That is to say, the base board formed by integrating the punching metal 1 with the nickel fibers and constituting the nickel fibers of a carbon fibers 2 and a nickel coating layer 3 is filled with the active material.
