“…[12] Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) is another commonly used salt for LMBs and has been reported for its good separator wettability and dendrite suppression. [13] Unfortunately, LiTFSI-based electrolytes come with a set of disadvantages for LMBs: 1) aluminum current collectors can corrode in LiTFSI-based electrolytes during cycling to form Al(TFSI) 3 and 2) dilute LiTFSI-based electrolytes give rise to an SEI layer that lacks LiF, which is an important component for a stable SEI layer. [9c,12,14] Apart from the mentioned lithium salts, several attempts have been made to improve performances of LMBs by incorporating new lithium salts.…”

“…On the basis of the previous studies [12][13][14][15][16]31], the solvent, the lithium-salt type and its concentration may affect the wettability determined by the contact angle. However, few systematic studies address the effect of salt concentration on surface tension and contact angle.…”

“…Wetting properties are determined by the contact angle [11]. Numerous studies show that insufficient wetting gives poor battery performance [12][13][14][15][16]. However, few systematic studies address the effect of salt concentration on surface tension and contact angle.…”

“…A smaller contact angle usually means higher wettability, which often connotes an improved cycle performance and lifespan of a cell. [ 69,99–101 ]…”
