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.
