为了解决锂离子电池首次充放电效率过低、不可逆容量损失会消耗大量电解液和正负极材料中脱出锂离子的问题,基于稳定化金属锂粉(SLMP)对硅电极进行预锂化,结合扫描电子显微镜(SEM)和X射线光电子能谱(XPS)对电极表面形貌...展开更多 为了解决锂离子电池首次充放电效率过低、不可逆容量损失会消耗大量电解液和正负极材料中脱出锂离子的问题,基于稳定化金属锂粉(SLMP)对硅电极进行预锂化,结合扫描电子显微镜(SEM)和X射线光电子能谱(XPS)对电极表面形貌及组成进行分析,探讨预锂化搁置时间及预锂化试剂用量对硅电极储锂性能的影响规律。研究表明,预锂化之后,减少了首次不可逆容量,提高了电极循环稳定...
