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. When the amount of mercury is large, with an emphasis on the corrosion inhibitory effect on zinc, the amalgamation rate (blinding rate) reached nearly 10% by weight (for example, "new battery", published by Tokyo Denki University Press). Issued by the Bureau, 1978, p. 42).
