【摘要】 锂离子电池储存后的性能会发生衰减。负极表面固体电解质膜(SEI)阻抗的增加是主要原因之一。本文研究了双草酸硼酸锂(LiBOB)作为成膜添加剂对锂离子电池储存性能的影响,结果表明,电解液中加入2wt%LiBOB后,电池的储存性能明显提高。更多还原

【Abstract】 The performances of lithium ion batteries would degradation after storage.The increasing impedance of solid electrolyte interphase(SEI)film formed on the anode surface is one of the main reasons for it.In this paper,the effects of lithium bis(oxatlato)borate(LiBOB)as a film-forming additive on the storage performance were studied,and the results show that the addition of 2 wt%LiBOB into the electrolyte can improve the storage performance of the batteries.更多还原
