A high-capacity enclosed nickel-zinc primary battery excellent in
characteristics such as capacity maintenance factor, energy density, and
high-efficient discharge characteristics, an anode using it, and a
production method for them. An enclosed nickel-zinc primary battery which
uses as an anode an anode active material of nickel hydroxide compound,
such as nickel oxyhydroxide, particles and uses zinc alloy gel as a
cathode material, wherein a ratio of anode theoretical capacity to
cathode theoretical capacity is 1.0-1.6, and a ratio of alkali
electrolyte to anode theoretical capacity is 1.0-1.6 ml/Ah.
