| Abstract: | The electrochemistry performance of self-made D size Ni/MH power battery was investigated. The results showed that the specific energy of battery stack was 58?Wh/kg and 199?Wh/L at 2.6?A discharge. It could be charged rapidly at 7.5?A (1C) and its discharge capacity at 7.5?A(1C),15?A(2C) and 37.5?A(5C) was up to 97.1%, 96.9% and 76.4% of that at 1.5?A((0.2?C).)The specific power of single battery was 488?W/kg.The decay of discharge capacity was 6% after 650 cycles of 100% DOD at 5?A. |
