杂质缺陷 meaning in English

extrinsic defect
impurity defect

It was found that the defects were formed and the conductivity increased with the addition of co , which improved the diffusion of proton and inhabited the formation of y - niooh . the electrochemical capacity of the electrode with cobalt additives changed slightly after 206 cycles . the electrode can exhibit excellent high - rate discharge performance , the capacity discharged at 6c ( 1800ma / g ) can reach to 77 . 7 % of which discharged at 1c condition
在纳米ni ( oh ) _ 2电极中加入钴和锌添加剂，并全面地分析了它们对电极性能的影响，发现加入钴添加剂后增强了电极的导电性，形成杂质缺陷，更有利于质子的出入，同时抑制- niooh的形成，提高充放电效率和循环稳定性，电极在经过206个循环后变化甚小；电极的倍率放电性能相当出色，在1800ma g ( 6c )的大电流放电条件下，依然能放出1c的77 . 7 ；在钴的添加方式中，以co和coo混合添加的效果最佳。
