In order to meet the demand for low temperature performance of MH/Ni batteries used in cold area, field work and military products, the technical staff of our company succeeds in developing the hydrogen storage alloy used in low temperature through three years’ hard work. The service temperature range of the product is between -40℃ to 80℃. In the room temperature, its discharge capacity is no less than 320mAh/g and the discharge capacity above 1.2V accounts for 80% or more of the total discharge capacity in 0.2C discharge rate; the cycle life of 1C charge and discharge cycle is more than 600 times. The best operating temperature of the product is 5℃ ~ 15℃, in which its discharge capacity is no less than 330mAh/g, the discharge capacity above 1.2V accounts for 85% or more of the total discharge capacity in 0.2C discharge rate, the cycle life of 1C charge and discharge cycle is more than 600 times. In 1C discharge rate, the discharge efficiency of this product is more than 80% at -20℃, and is no less than 65% at - 40℃. After this product appears on the market, it is warmly welcomed by the battery manufacturers in European countries and by those who produce military batteries. Now, this product has already been steadily used in the production of military batteries, and it has already been supplied to the domestic and international markets in large quantities.
