Alkaline storage battery

摘要

An alkaline storage battery configured with an improved nickel positive electrode plate having a high capacity density and a high utilization of the active material is disclosed. The nickel positive electrode plate comprises a porous metal plaque, a first layer of nickel hydroxide loaded in close proximity to inner surfaces of pores of the porous metal plaque, and a second layer of nickel hydroxide loaded over the first layer. The nickel hydroxide in the second layer has a larger particle diameter than that in the first layer, and the amount of the nickel hydroxide in the second layer occupies a majority of the total amount of the active material filled in the positive electrode.
