中文摘要:

铁酞毒(FePc ) 和内部压力和封上的 Ni-MH 电池的周期行为上的钴卟啉(CoPp ) 的效果在这研究被调查。电池电极的 Themorphology 被 SEM 观察。电气化学的阻抗光谱学 offloating-charge/discharge 电池也被测量。试验性的结果证明到合金电极的增加 ofFePc 或 CoPp 是一条有效途径减少电池的内部压力在充电和过高的要价的过程期间。与 CoPp 相对照,有 FePcexhibits 的电池在一样的费用分泌物的更慢的能力腐烂和更小的过电位评价。Asan 电镀物品催化剂, FePc 可以更有效地加快氧,和减少的减小它的还原电位。作为结果,费用过程被加速,煤气的进化被减少,电极材料的弄成粉被减慢。

英文摘要:

The effects of iron phthalocyanine (FePc) and cobalt porphyrin (CoPp) on inner pressure and cycle behavior of sealed Ni-MH batteries were investigated in this study. The morphology of battery electrode was observed by SEM. The electrochemical impedance spectroscopy of floating-charge/discharge battery was also measured. Experimental results show that the addition of FePc or CoPp to the alloy electrode is an effective approach to decrease the internal pressure of battery during the process of charge and overcharge. In contrast to CoPp, the battery with FePc exhibits a slower capacity decay and a smaller overpotential at the same charge-discharge rate. As an electrocatalyst, FePc may more effectively speed up the reduction of oxygen, and decrease its reduction potential. As a result, the charge process is accelerated, the gas evolution is reduced and the pulverization of electrode materials is slowed down.
