The different electrolyte formula effects on self-discharge properties of the nickel-metal hydride batteries in earlier and later periods are stadied.At the same time

the capacity-keeping rate of the battery with different electrolyte formula at different temperatures are researched.The results show that the capacity-keeping rate of the nickel-metal hydride battery has upward trend with the increase of the proportion of NaOH

and the capacity-keeping rate in the earlier period is higher than that...
