Outline
In order to improve the charge discharge efficiency of nickel metal hydride (Ni-MH) battery at high temperature and meet the requirements of service environment, the charge and discharge performance of Ni-MH battery at high temperature are tested by adding NaOH into the conventional electrolyte. The experiment of comparing the charge discharge efficiency of Ni-MH battery added NaOH electrolyte with that of conventional Ni-MH battery is carried out at the environment temperatures of 55 ℃ and 65 ℃ separately. The results showed that the charge and discharge performance of Ni-MH battery added NaOH electrolyte was obviously higher than that of conventional Ni-MH battery in high temperature environment. The charge discharge efficiency is about 3 percentage points higher than that of conventional battery in high temperature environment of 55 ℃ and it is about 17~20 percentage points higher than that of conventional battery in high temperature environment of 65 ℃.
