Abstract

An alkaline storage battery which includes a positive electrode, a negative electrode including a hydrogen absorbing alloy containing manganese as an active material, a separator and an alkaline electrolyte and contains a complex-forming agent which does not include nitrogen and which creates a complex with manganese. To provide an alkaline storage battery using a hydrogen storage alloy containing manganese as a negative electrode, restrained from deposition of dissolved manganese on a separator after repetitive charge and discharge, preventing a complexing agent from decomposition and becoming an impure ion, and restrained from self discharge to improve a preservation property or the like.

Description

technical field [0001] The present invention relates to an alkaline storage battery, which is an alkaline storage battery having a positive electrode, a negative electrode with a hydrogen storage alloy as an active material, a diaphragm, and an alkaline electrolyte, and is particularly characterized in that the hydrogen storage alloy of the negative electrode contains manganese In some cases, the precipitation of manganese leached from the hydrogen storage alloy through charge and discharge on the separator can be suppressed, thereby suppressing the self-discharge phenomenon. Background technique [0002] In recent years, alkaline storage batteries are widely used in portable machines and electric vehicles. Compared with nickel-cadmium storage batteries, this alkaline storage battery has the advantages of high capacity and good environmental safety. Therefore, this kind of hydrogen storage alloy is used as the negative electrode Alkaline batteries are gradually being widely ...
