By analyzing the composition, particle size, specific surface area and P-C-T curve of low temperature alloy and conventional alloy, it is proved that low temperature alloy can improve the low temperature performance of Ni-MH battery. The specific power and high current discharge performance of Ni-MH battery were greatly improved through the electrochemical performance test of two kinds of alloy powder and the performance test of Ni-MH battery. The discharge rate of Ni-MH battery could reach more than 80% at -40 鈩，
