A HIGH-TEMPERATURE NICKEL-HYDROGEN BATTERY AND PRODUCING METHOD THEREOF

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.
