PROBLEM TO BE SOLVED: To prevent a possibility of causing liquid leakage due to heat generation by a large electric current flow, when an alkaline dry battery is externally short-circuited erroneously, as well as to prevent the deterioration of an ordinary general discharge characteristic. SOLUTION: Thermoplastic resin powder, for example, low density polyethylene having a melting point of not more than 130 deg.C is arranged in a layer shape at least in one place among an interface between a hollow cylindrical positive electrode mix 2 and a bottomed cylindrical separator 3 of an alkaline dry battery, an interface between the bottomed cylindrical separator 3 and a gel-like zinc negative electrode 4 and the inside of the bottomed cylindrical separator. If the battery is heated abnormally, a thermoplastic resin softens and melts, and controls heat generation by cutting off electric current. |
