PURPOSE:To improve impact resistance characteristic and discharge characteristic at a low temperature by forming the negative pole by dispersely mixing together the specified amount of electrolyte polymer, short fiber in the specific weight and diameter and zinc powder respectively in relation to a certain amount of the alkaline electrolyte. CONSTITUTION:A gel negative pole is formed by dispersely mixing, with the alkaline electrolyte, an electrolytic polymer such as the Na salt of carboxylmethylcellulose of 1.3-2.6wt% in relation to the amount of electrolyte, short fiber having eliminated the element which is soluble in the alkaline electrolyte and of 1.0-3.0vol% with diameter of 10-30mum in relation to the amount of the electrolyte and the zinc powder. A positive pole black mix 2, a separator 3 and an electrolyte-impregnated material 4 are combined and thereby a button type alkaline battery is formed. Accordingly, the impact resistance characteristic can be improved, and gel viscocity can be lowered by suppressing addition of electrolyte polymer because the zinc particles are held uniformly with addition of short fiber, thus a high load discharge characteristic at a low temperature can be enhanced. |
