摘要
Abstract
In this paper, the effects of overcharge, charge-discharge C rate and pore size 4.5＇ electrochemical impregnated nickel electrode were investigated. In the case of the on cycle lifetime of electrode was overcharged to 170% of nominal capacity,the initial capacity of the electrode could be maintained 2.7 Ah up to 150 cycles without deterioration and a discharge capacity of 1.7 Ah （remaining 63% of 2.7 Ah ） could be delivered after 300 cycles. Without overcharge, more than 300 charge-discharge cycles could be realized without loss of capacity and a discharge capacity of electrode could be maintained about 76% of initial capacity even after 1000 cycles. The experimental results also showed that without overcharge the increase in pore size and activation with small current could improve the electrode cycle capability.关键词
