Abstract
An alkaline storage battery includes a positive electrode, a negative electrode, a separator, and an alkaline electrolyte retained in the positive electrode, the negative electrode, and the separator. The alkaline storage battery further includes a first compound for adsorbing ammonia between the positive electrode and the negative electrode. The positive electrode comprises a second compound for increasing oxygen overvoltage at a time of overcharge. Thus, an alkaline storage battery with particularly little self-discharge can be provided.
