  • High-temperature Ni-MH battery and a method for making the same
    Patent number: 6689514
    Abstract: The present invention relates a high-temperature Ni—MH battery and the method for making the same. By adding a titanium additive in the anode materials at an amount of 0.1-15.0% (weight), based on the weight of the active spherical nickel hydroxide, the high-temperature charging efficiency of the Ni—MH battery can be greatly improved. The charging efficiency of the Ni—MH battery of the present invention can reach 95% at a temperature higher than 50° C. The Ni—MH battery of the present invention can be used at a temperature of 50° C. or higher.
