| 中文摘要 | The La1-xCex(NiCoMnAl)(5) alloy electrodes were treated by hot charging in alkaline aqueous solution containing KBH4. The activation behavior, hydrogen diffusion coefficient and maximum discharging capacity, high rate discharging capability of alloy electrodes were tested. The surface morphology and element content were observed by scanning electron microscope. The results show that the alloy electrode is fully activated after the second charging-discharging cycle and has a high rate discharging capability of 85 % at 900 mA/g. The surface has a lot of micro-cracks and hydrogen diffusion coefficient is about (2 similar to 3) x 10(-9) cm(2)/s. Therefore, this method can markedly improve activation behavior and high rate charging capacity of the alloy electrode. The mechanism of this surface modification of the alloy electrode is also discussed. |
