Electrochemical impedance spectroscopy and cyclic voltammetry were used to study the effect of different methanol impurity contents on the performance of graphite electrode and its mechanism in 1 mo only L LiPF "EC/DEC/DMC electrolyte. The effect is related to the content of methanol in the electrolyte; the mechanism of its effect on the performance of the graphite electrode is that the lithium methoxylide generated by the reduction of methanol at about 2.0 V is deposited on the surface of the graphite electrode, forming an initial SEI film, which affects the reduction of EC. Decomposition into film process.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and has a unique packed column in the R&D department for the determination of methanol in electrolyte. It has high column efficiency, good separation, and symmetrical peak shape. Methanol appears behind a large amount of solvent moisture, which is reasonable. Quantitatively accurate and reliable.
