Abstract: 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.

Abstract: The object of the invention is to provide an alkali primary battery being excellent in high rate discharge characteristics with less increase of the inner pressure by generating hydrogen in the overdischarge process. The invention provides a sealed nickel zinc primary battery comprising at least a positive electrode having a higher oxide of nickel as a positive electrode active substance, a negative electrode having zinc or an alloy thereof as a negative electrode active substance, a separator and an electrolyte solution housed in a vessel, wherein manganese dioxide is added in a proportion of 3 to 7% by mass relative to the higher oxide of nickel in the positive electrode, and the ratio between the theoretical capacity of the negative electrode to the theoretical capacity of the positive electrode (the theoretical capacity of the negative electrode/theoretical capacity of the positive electrode) is in the range of 1.2 to 1.0.

Abstract: In a battery in which a metallic battery case for accommodating electricity-generating elements also serves as an electrode, a visible-light or near-infrared-light curing resin is used for providing a coating to insulate an end face and a peripheral edge portion of an opening portion of the battery case or a gap between a positive electrode and a negative electrode. The visible-light or near-infrared-light curing resin excels in a depth-curing characteristic as compared with a conventional ultraviolet curing resin, and cures well even up to a portion such as an insulating seal of a battery where a light-receiving port is light and the light is difficult to reach. Hence, the visible-light or near-infrared-light curing resin is prevented from becoming peeled off and provides a reliable insulting characteristic.
