酯類電解液添加劑

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

過去的研究表明硼酸鹽添加劑可以抑制錳，鎳的溶解，同時可以抑制碳酸鹽溶劑的分解，形成穩(wěn)定且薄的CEI膜。本文從XRD,XPS，SEM,TEM等表征解釋ADM添加劑在電化學性能差異的原因。P.S.? TEM的CEI膜表征可商榷。

醚類電解液添加劑

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

本文設計了含偽冠醚的帶正電的部分以及帶負電的三氟磺?；糠?，正負電荷

DN供電子數(shù)測算：23Na NMR ，將溶液和溶質(zhì)看成一個整體

給電子基團有助于無機物鋰鹽的溶解，提高鋰離子轉(zhuǎn)移數(shù)目。

SEI膜中有機物比較脆，不穩(wěn)定。

總結(jié)醚類添加劑的兩大原因：促進硝酸鋰在酯類電解液的溶解，清除SEI表面有機物，形成更穩(wěn)定的無機+有機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.
