Abstract
Изобретение относитс к никель- цинковым аккумул торам. Цель изобретени - увеличение срока службы. В электролит никель-цинкового аккумул тора, содержащий гидроксид кали и оксид цинка, вводитс добавка ал- килполипропиленгликолевых эфиров общей формулы СпН^„„ (OCjH, )^ОН, где п» =7-12, т=10-20, в кол-ве 1,0-3,0г/л. Эта добавка св зывает образующиес • дендриты цинка, преп тству их росту, и тем самым исключает короткие замыкани в аккумул торе. I табл.The invention relates to nickel-zinc batteries. The purpose of the invention is to increase the service life. The electrolyte of the nickel-zinc battery containing potassium hydroxide and zinc oxide is supplemented with the alkylpolypropylene glycol ethers of the general formula CpN ^ ni (OCjH,) ^ OH, where n = 7-12, m = 10-20, per -ve 1.0-3.0g / l. This additive binds the resulting zinc dendrites, preventing their growth, and thereby eliminates short circuits in the battery. I table
