摘　　要：电池充放电过程中正极电位偏离平衡电极电位较为明显,电池会因为充放电效率低而发热。笔者试图将石墨烯加入正极中对此进行改善。结果显示,石墨烯能在一定程度上提高正极充放电效率,且对于电池的化成过程也有一定程度的改善,但结果不十分明显。另外,提出了充放电效率及电池发热情况的试验方法。During charge and discharge process,the positive electrode potencial deviates from the balanced electrode potencial very obviously,and the battery will generate heat owing to the low charge and discharge ef ficiency.The author tried to add the graphene additives into the positive electrode to improve this condition,and the result indicates that the additives are bene ficial to increasing the charge and discharge ef ficiency for positive electrode and the battery formation process in a certain extent,but there is no notable effect.Moreover,this paper presents a test method for charge and discharge efficiency and the battery heating state.
