Title: Manufacture of positive plate for lead storage battery
Inventor: HIRASAWA IMAKICHI
IPC: H01M4/20
Filed: 1982-05-25
Abstract: PURPOSE:To enhance the utilization rate of an active material, and increase the mechanical intensity of the interface between a base body and the active material by making a lead powder or positive paste slurry-like matter containing minute grains of a resin to adhere to the surface of the base body, being followed by packing a positive paste into the base body. CONSTITUTION:As minutely granulated resins, thermoplastic synthetic resins such as polyvinylchloride may be employed. At least one kind of such minutely granulated resins and lead powder or a positive paste are homogeneously and sufficiently dispersed in a solvent by use of a proper dispersing agent. Next, a base body is dipped in the thus prepared slurry-like matter so as to cause the slurry-like matter to homogeneously adhere to the surface of the base body. Either directly after that or after the solvent is evaporated, the positive plate is placked into the base body. The micro-granular resin held near the base body together with lead powder or the positive paste, is moten by being maintained at over its melting point to block part of the fine holes formed in the paste located near the base body, and locally decrease the porosity of the paste. Owing to such a reduced porosity of the active material, diffusion of sulfuric acid is suppressed and the active material is prevented from being overused during charging.
