To provide a charging characteristic improving agent by which charging receiving performance of a nickel positive electrode can be improved, and an alkaline battery which can exhibit excellent charging receiving performance and a battery characteristic.
In a charging characteristic improving agent to improve a charging characteristic of an alkaline battery, the charging characteristic improving agent has one kind or two or more kinds of oxides or hydroxides selected from a group of Sr, Sc, lanthanoid, Al, Ga, Ti, Zr, Nb, Bi and Ir. The charging characteristic improving agent is added to either of electrolyte to flow electricity between a nickel positive electrode and a negative electrode when the nickel positive electrode, the negative electrode and a salute dissociate in an ionic shape or a separator arranged between the nickel positive electrode and the negative electrode.
