“…Among these, ethylene sulfi te (ES) is one of the practical anode SEI-forming additives [ 158 ], and dimethyl sulfi te is a promising candidate as a co-solvent that improves low-temperature performance of graphite/LiCoO 2 cells [ 159 ]. (e) Sulfonates Due to the high chemical reactivity of sulfonates, they are not easy to use as electrolyte solvents.…”

Most of the liquid electrolytes used in commercial lithium-ion (Li-ion) cells are nonaqueous solutions, in which roughly 1 mol dm −3 of lithium hexafl uorophosphate (LiPF 6 ) salt is dissolved in a mixture of carbonate solvents selected from cyclic carbonates-ethylene carbonate and propylene carbonate-and linear carbonates-dimethyl carbonate, ethyl methyl carbonate, and diethyl carbonate. In Sect. 2.1, the physicochemical properties of these carbonate solvents are listed and the phase diagrams and electrolytic conductivity data of mixed carbonate solvent systems are given. However, recent market demands for Li-ion cells with higher energy, higher power, and higher safety requires new solvents to improve the performance of cells in electrolytes based on carbonate solvents only. New heteroatom-containing organic solvents including fl uorine, boron, phosphorous, and sulfur, which have been applied to lithium cells in recent years, are reviewed from the viewpoints of synthesis, physicochemical properties, and cell performance by four authors.

“…As film-forming additives, PS and ES have been approved effectively in improving the charge/discharge performance of LiCoO 2 /C cell [24]. From the changes of S2p analysis, it could be concluded that the SEI species formed from reduction of other compositions of electrolyte may partly dissolve in the electrolyte.…”

“…They found that both ES and VC caused detrimental effects to the sodium‐ion cells by using hard carbon as an anode and NaNi 1/2 Mn 1/2 O 2 as a cathode . Both of these additives exhibit improved cycling performance in a lithium‐ion battery . They proposed that a different approach was required for interfacial control of sodium insertion electrodes compared with that of the lithium‐ion battery.…”

The solid-electrolyte interface (SEI) film in a sodium-ion battery is closely related to capacity fading and cycling stability of the battery. However, there are few studies on the SEI film of sodium-ion batteries and the mechanism of SEI film formation is unclear. The mechanism for the reduction of ethylene carbonate (EC), propylene carbonate (PC), vinylene carbonate (VC), ethylene sulfite (ES), 1,3-propylene sulfite (PS), and fluorinated ethylene carbonate (FEC) is studied by DFT. The reaction activation energies, Gibbs free energies, enthalpies, and structures of the transition states are calculated. It is indicated that VC, ES, and PS additives in the electrolyte are all easier to form organic components in the anode SEI film by one-electron reduction. The priority of one-electron reduction to produce organic SEI components is in the order of VC>PC>EC; two-electron reduction to produce the inorganic Na CO component is different and follows the order of EC>PC>VC. Two-electron reduction for sulfites ES and PS to form inorganic Na SO is harder than that of carbonate ester reduction. It is also suggested that the one- and two-electron reductive decomposition pathway for FEC is more feasible to produce inorganic NaF components.
