(4) HClO


D．放电时，正极反应为3CO2+4Li++4e-=2Li2CO3+C
【答案】C
【解析】放电时二氧化碳得到电子发生还原反应为正极，正极电极反应式：3CO2+4Li++4e -=2Li2CO3+ C，锂失去电子发生氧化反应，为负极，负极反应式：Li-e -=Li+。Li是活泼金属，能与水反应，不能用水溶液作电解质，可使用有机电解液，A正确；充电时，原电池的负极与电源的负极相连，作阴极，原电池的正极与电源的正极相连，作阳极，阳离子向阴极移动，故充电时，Li+ 由正极向负极迁移，B正确；由正极反应历程可知，C为最终产物，*LiCO2、*CO、*LiC2O3是中间产物，共
3种，C错误；由分析可知，正极电极反应式：3CO2+4Li++4e -=2Li2CO3+ C，D正确。
