【摘要】 本文研究了首次充电电流对LiCoO₂/石墨电池性能的影响。研究结果表明,随着首次充电电流的增加,电池首次充放电库仑效率变大,但是第二次库仑效率变小;电池在25℃下的循环性能几乎不随首次充电电流的变化,然而电池50℃的循环性能随着首次充电电流增加明显变差。更多还原

【Abstract】 The effect of the first charge current on the performance of LiCoO₂/graphite battery was studied in this paper.Results show that the coulombic efficiency of first charge and discharge increases with the increase of the first charge current,whereas the coulombic efficiency of second charge and discharge decreases.The cycle performance of the battery at 25℃almost does not change with the change of charge current,whereas the cycle performance of the battery at 50℃become obviously bad with increase of first charge current.更多还原
