Abstract

본 발명은 니켈도금액과 전극재료인 LaNi4.7Al0.3합금분말을 혼합하여 철그물망에 도금하므로서 전극성형시 전극물질의 박리를 방지하고 전기전도성을 개선하고자 발명한 건전지의 전극제조방법에 관한 것으로, 즉 도금조내에 니켈도금액과 전극재료인 LaNi4.7Al0.3합금분말을 혼합하여 300g/ ι의 농도로 현탁시키고, 그 도금조내에 양극은 니켈판으로, 음극은 철그물망으로 전원을 공급하는 동시에 공기를 공급시켜 합금분말이 고르게 분산되도록 하여 니켈도금층이 형성되도록 하여 전극을 제조한다.The present invention relates to a method for manufacturing an electrode of a battery invented by mixing a nickel plating solution and LaNi 4.7 Al 0.3 alloy powder, which is an electrode material, and plating it on an iron mesh net to prevent peeling of the electrode material and to improve electrical conductivity when forming an electrode. In other words, the nickel plating solution and LaNi 4.7 Al 0.3 alloy powder, an electrode material, are mixed and suspended in a plating bath at a concentration of 300 g / ι. In the plating bath, the anode is supplied with a nickel plate and the cathode is supplied with an iron mesh net. To supply an evenly dispersed alloy powder to form a nickel plated layer to produce an electrode.
