Effect of discharge current on the cathodic process 祖延兵 1 first-author 董庆华 1 武汉大学化学系 武汉大学化学系 Department of Chemistry, Wuhan University Department of Chemistry, Wuhan University 利用光电化学方法和Ｘ射线衍射分析方法，研究了锂－氧化钢电池阴极还原反应．发现采用不同电流密度放电，该电池阴极过程有较大差别：放电电流密度较小时，电化学嵌入反应是主要的阴极过程；随放电电流密度的增大，经典的还原反应以越来越大的比例加入到放电过程中来．据此解释了文献报道中存在的一些矛盾现象． The cathodic processes of Li-CuO Cells partially discharged with different current density have been investigated by photoelectrochemical technique and X-ray diffraction method. It is found that the reduction of CuO cathode is mainly the electrochemical intercalation reaction under the condition of low discharge current density,and the classical reduction of CuO electrode takes place and plays more and more important role with the increase of current density. According to the results,the contradiction in literature is discussed. 锂－氧化钢电池 电极反应机理 光电化学方法 X射线衍射分析 Li-CuO cell mechanism of electorde reaction photoelectrochemical technique X-ray diffraction analysis O646.541 国家自然科学基金(61672102) 1995-02-01 2021-04-01 2
