2. Description of the Related Art Conventionally, in alkaline batteries using zinc as a negative electrode active material, the surface of zinc particles has been amalgamated with mercury in order to suppress generation of hydrogen gas due to corrosion of zinc. And, the amount of mercury reached about 10% by weight in terms of the amalgamation rate (degradation rate) when the amount of mercury was large, placing importance on the corrosion inhibition effect on zinc (for example, "new battery", published by Tokyo Denki University Press). Issued by the Bureau, 1978, p. 42).
