PURPOSE:To obtain an alkaline battery such as an alkaline manganese battery or mercury battery which shows an excellent characteristic when used for a large consumption current, without deteriorating the preservation reliability of the battery, by homogeneously dispersing cellulose powder in the gel-like electrolyte of the battery. CONSTITUTION:The symbol 1 represents a metallic sealing plate also serving as a negative terminal. The symbol 2 represents a sealing gasket which insulates the positive electrode from the negative electrode and seals the opening of a case. The symbol 3 represents a cylindrical metallic case which has a bottom and gives pressure upon a positive mixture 4. A separator 5 is placed on the upper surface of the positive mixture 4, and an electrolyte holding member 6 is placed on the upper surface of the separator 5. The symbol 7 represents a positive ring with which the positive mixture 4 is fixed to the case 3. The symbol 8 represents a negative part which contains amalgamated zinc powder, alkaline electrolyte, and slight amounts of a gelling agent and cellulose powder. By thus dispersing cellulose powder in the negative part 8,the discharge performance of the negative part 8 is remarkably improved especially at low temperature. Besides, the battery has an outstanding preservation capacity, and shows an excellent performance when used for a large consumption current. |
