研究333K时Ti0.17Zr0.08V0.35Cr0.1Ni0.3合金的循环稳定性和高温倍率放电性能。333K时,当放电电流密度为60mA/g时,Ti0.17Zr0.08V0.35Cr0.1Ni0.3合金第1次放电容量为450mAh/g。随着充放电循环的进行,放电容量迅速降低。当放电电流密度为2400mA/g,截止电压为0.6V时,Ti0.17Zr0.08V0.35Cr0.1Ni0.3合金的放电容量仍达到160mAh/g。并详细探讨影响以上合金电化学性能的因素。

英文摘要：

The cyclic stability and the high-rate discharge characteristic of Ti0.17Zr0.08V0.35Cr0.1Ni0.3 alloy at 333 K were investigated. The results show that the discharge capacity of Ti0.17Zr0.08V0.35Cr0.1Ni0.3 alloy is ~450 mAh/g at a current density of 60 mA/g at 333 K for the first cycle,and then it obviously decreases with increasing of cycle number. It should be noted that the excellent discharge capacity of Ti0.17Zr0.08V0.35Cr0.1Ni0.3 alloy will remain 160 mAh/g at a current density of 2400 mA/g to cut-off voltage of 0.6 V. Moreover,the possible factors affecting the electrochemical performance of this alloy were discussed.
