Title:
AIR-ZINC BATTERY AND MANUFACTURING METHOD OF OXYGEN ELECTRODE OF THE SAME
Document Type and Number:
Japanese Patent JP2003068372
Kind Code:
A
Abstract:

To extend the life of an air-zinc battery when discharged at a high temperature.

Related to an air-zinc battery, with oxygen as the positive-pole active material and zinc as negative-pole active material, an electrode layer 14 which reduces the positive-pole oxygen at least comprises a catalyst layer 6 which adsorbs and reduces oxygen and a water-repellent layer 8 which is press-fitted to the catalyst layer. The material whose Gurley value is 50-500 seconds is used as the water-repellent layer 8 press-fitted to the catalyst layer 6 to form an electrode layer. Thus, the electrolyte is prevented from accumulating between the catalyst layer and the water-repellent layer, to extend its life shortened by discharging at a high temperature.
