NICKEL-ZINC SECONDARY BATTERY

摘要

PURPOSE: Provided is a nickel-zinc secondary battery used as power for electric cars, which optimizes the amount of electrolyte in the balance of a battery lifetime and a discharging performance, therefore, the lifetime of the battery can be extended. CONSTITUTION: The nickel-zinc secondary battery contains a nickel anode(1) covered with a polypropylene nonwoven fabric(4) and a zinc cathode(2) covered with a cotton fabric(3) and the polypropylene nonwoven fabric(4), which are covered with a polypropylene microcellular film(5). The ratio of the electrolyte amount impregnated into a separator and the total electrolyte amount of the battery is 0.15-0.28. And the volume of the electrolyte per 1Ah of the zinc cathode(2) is 1.03-1.33ml.
