【Abstract】

<正> The properties of MH/Ni batteries using different separator were studied. And then an idea for choosing separator for high-power MH/Ni battery was provided. Using the separator with grafting treatment, the storage characteristic , charge retention characteristic and anti-soft-short characteristic of high-power MH/Ni battery are improved. Wetlaid and spunfibre material meet different properties requirement of battery.
