“…In LEs, the primary role of VC is to act as an artificial SEI layer forming agent over the anode surface; in this case, it is Li-metal. [407][408][409] Here, as the rate of polymerization reaction of methacrylate is very high and the concentration of VC in the precursor is very low, it is not expected that the VC molecule will become a part of the main chain of the polymer network. Although not explicitly mentioned, the presence of VC in this work is expected to mitigate/minimize any undesirable passivation (by dimethacrylate) over the Li-metal anode.…”

“…However, the exact structure and thickness is not clear due to its varying nature that is dependent on cathode materials and cycling parameters. The protective nature of this passivation layer is distinct to prevent further electrolyte decomposition and self-discharge of cathodes [28,[67][68][69][70][71].…”

Lithium ion batteries (LIBs) are widely used in numerous application areas, including portable consumer electronics, medicine, grid storage, electric vehicles and hybrid electric vehicles. One major challenge during operation and storage is the degradation of the cell constituents, which is called aging. This phenomenon drastically reduces both storage lifetime and cycle lifetime. Due to numerous aging effects, originating from both the individual LIB cell constituents as well as their interactions, a wide variety of instruments and methods are necessary for aging investigations. In particular, chromatographic methods are frequently applied for the analysis of the typically used liquid non-aqueous battery electrolytes based on organic solvents or ionic liquids. Moreover, chromatographic methods have also been recently used to investigate the composition of electrode materials. In this review, we will give an overview of the current state of chromatographic methods in the context of LIB cell research.

, M＝Mn, NMC; M＝Al, NCA)} are one of the most promising cathode materials of lithium-ion batteries (LIBs). However, in the traditional electrolyte system, they will undergo dramatic structural changes and interface side reactions at high potential and high temperature, which will bring great challenges to their practical application, especially for their cycle life and safety. Developing appropriate electrolyte additive is one of the most economical and effective methods to improve the electrochemical performance of LIBs. Based on the intrinsic structure of material, electrolyte additives used for NMC and NCA ternary cathode and their reaction mechanism in the past 5 years are reviewed in this paper, which include vinylene carbonate (VC), fluoro-compounds, new lithium salts, P-based, B-based, S-based, nitrile, others and combinative additives. Among them, VC becomes a kind of universal additive, which can improve the efficiency and cycle life at low voltage and normal temperature. Fluoro-compounds have been developed from mono substituted such as Fluorinated ethylene carbonate (FEC) to multi-fluorine substituted, which can improve the stability of electrode/electrolyte interface under high voltage. New lithium salt additives are mainly used to improve the film forming performance under high voltage and high temperature, such as Lithium bis(fluorosulfonyl)imide (LiFSI), Lithium difluorophosphate (LiDFP). P-contained additives [such as Tris(trimethylsilyl)phosphite (TMSPi)] are mainly to improve the stability of anode-electrolyte interface, and it has obvious synergistic effect when they combined with additives such as VC. B-contained additives are mainly used to improve the dissociation degree and stability of lithium salt, such as Tris(trimethylsilyl)borate (TMSB). S-contained additives are mainly used to improve the ionic conductivity and stability of anode SEI film, such as Prop-1-ene-1,3-sultone (PES). Nitriles are benefited from the strong electron withdrawing effect of -CN, which can improve the stability of the electrode/electrolyte interface at high voltage. Other types of additives are some heterocyclic compounds having film forming ability and various silanes which can eliminate HF and H 2 O. Combinative additives are developed from VC based composite to PES and PBF (pyridine boron trifluoride) system, which can endure even harsher conditions.
