| Abstract: | The effects of the surface treatment of hydrogen storage alloy powders using KBH4 as reductant in alkaline solution on the performances of MH/Ni battery were investigated. It was found that the surface modification raised the charge/discharge cycle life and discharge voltage,and improved considerably the high - rate dischargeability and low temperature characteristics. The mechanism of effects on the performances of battery was discussed with previous research. |
