| 摘 要： | 利用化学镀方法在石墨粉表面镀覆了一层均匀、完整的金属镍，研究了镀镍石墨粉电极及镀镍石墨粉作为ＭＨ／Ｎｉ电池镍电极导电剂时的电化学性质。实验表明，石墨粉表面镀覆金属镍可增另其电化学活性；用镀镍石墨粉作为电极导电剂时，可以改善镍电极的导电性能，降低电池内阻，提高正极活性物质的利用率，且电池的循环稳定性好，以１Ｃ倍率充放电循环１２０就衰减。

| Abstract: | The electrochemical characteristics of nickel electroless plating graphite powder was investigated. Experiments showed that the electrochemical activity of the powder coated with nickel is increased, the resistance of the battery is reduced, the utilization factor of the active materials in the positive electrode is increased and electrochemical cycle performance is improved when the nickel coated powder is used as the conductive agent of the positive electrode of MH/Ni batteries. |
