酯类电解液添加剂

Methylboronic acid MIDA ester (ADM) as an effective additive in electrolyte to improve cathode electrolyte interlayer performance of LiNi0.8Co0.15Al0.05O2 electrode

过去的研究表明硼酸盐添加剂可以抑制锰，镍的溶解，同时可以抑制碳酸盐溶剂的分解，形成稳定且薄的CEI膜。本文从XRD,XPS，SEM,TEM等表征解释ADM添加剂在电化学性能差异的原因。P.S.  TEM的CEI膜表征可商榷。

醚类电解液添加剂

Designing an asymmetric ether-like lithium salt to enable fast-cycling high-energy lithium metal batteries

本文设计了含伪冠醚的带正电的部分以及带负电的三氟磺酰基部分，正负电荷

DN供电子数测算：23Na NMR ，将溶液和溶质看成一个整体

给电子基团有助于无机物锂盐的溶解，提高锂离子转移数目。

SEI膜中有机物比较脆，不稳定。

总结醚类添加剂的两大原因：促进硝酸锂在酯类电解液的溶解，清除SEI表面有机物，形成更稳定的无机+有机SEI膜。

As for advanced LiFEA electrolytes, LiFEA served two critical functions: boosting LiNO3 solubility in carbonate electrolytes and cleaning undesirable organics in the SEI.
