PURPOSE:To reduce the amalgamation ratio of negative electrode zinc and obtain a battery with low pollution by adding specific elements to the negative electrode of a zinc alkaline battery. CONSTITUTION:The negative electrode 2 of a zinc alkaline battery uses a zinc alloy in which one or more elements such s aluminum or magnesium and one or more elements selected from a group made of cadmium, lead, and tin are added. As a result, a zinc negative electrode with both excellent resistance to corrosion and discharge performance can be achieved in low amalgamation ratio and the zinc alkaline battery with low pollution that hardly generates the expansion, liquid leakage, and self-consumption caused by the zinc corrosion and gas generation and is excellent in the discharge performance can be obtained. |
