Abstract

PURPOSE:To uniformly scatter a negative electrode active material and obtain a battery with excellent discharge performance and low temperature performance by mixing and agitating the alkaline solution in which a first gelling agent is dissolved, and a mixture of the second gelling agent and the negative electrode active material. CONSTITUTION:The first gelling agent such as carboxymethylcellulose is dissolved in an alkaline solution such as caustic potash to prepare a viscous electrolyte. This viscous electrolyte, and a mixture of the second gelling agent such as sodium polyacrylate, carboxyvinyl polymer, or the like and negative electrode acitve material powder are mixed, agitated and gelatinized to form a gell-like negaive electrode 5. For example, a viscous electrolyte in which 20g carboxymethylcellulose is dissolved in 1kg caustic potash electrolyte, and zinc amalgam powder coated with carboxyvinyl polymer are mixed and agitated and the gell-like negative electrode is produced.
