But the concentration of Li2CO3 remains nearly consistent and a new component, CH3OLi, is found in SEI. It can be concluded from these results that anisole reacts with the reduction product of EC and DEC, RCO3Li, in the first process of Li＋ intercalating into the carbon electrode. The obtained CH3OLi is helpful in building up a more effective and stable SEI of the carbon electrode, reducing the cointercalation of solvent molecular. All these contribute to the improvement of the cycle performance of lithium-ion battery.

根据以上分析结果，提出了苯甲醚对锂离子电池循环性能的影响机理：在Li＋嵌入石墨电极的初次过程中，苯甲醚和EC、DEC的还原分解产物RCO3Li发生基团交换反应，生成CH3OLi，该产物能有效提高石墨电极表面SEI的稳定性，减少锂离子嵌入石墨过程中引起的溶剂分子共嵌入，从而改善电池的循环性能。
