An alkaline battery comprises a negative electrode having an active material comprised of mercuryless zinc powder, and an electrolyte. In one embodiment, the electrolyte contains one or more indium compounds selected from the group consisting of indium sulfate, indium sulfamate and indium chloride. In another embodiment, the negative electrode contains one or more indium compounds selected from the group consisting of indium sulfate, indium sulfamate and indium chloride. An improved alkaline battery is achieved which does not pose environmental problems, in which corrosion of the zinc powder by the electrolyte during storage of the battery is suppressed, and in which a good discharge performance of the battery is maintained.
