Lithium 4-pyridyl trimethyl borate

WebLinear sweep voltammetry (LSV) suggests that incorporation of the lithium borates into 1.2 M LiPF6 in EC/EMC (3/7) electrolyte results in borate oxidation on the cathode surface at high potential. The reaction of the borates on the cathode surface leads to an increase in impedance as determined by electrochemical impedance spectroscopy (EIS), consistent … Web16 okt. 2024 · Lithium bis (oxalate)borate (LiBOB), the first nonfluorinated salt attracted significant interest, which was reported in a German patent by Metallgesellschaft AG in 1999 [33]. Subsequently, researchers found that the excellent ability of film formation derived from LiBOB can protect graphite from exfoliation even in neat propylene carbonate [34].
