New insights into the electroreduction of ethylene sulfite as an electrolyte additive for facilitating solid electrolyte interphase formation in lithium ion batteries

The electroreduction of ES, an additive of the electrolyte of lithium-ion batteries was theoretically reinvestigated. The newly located concerted pathway has lower energy barrier than the stepwise pathway in literature.

Effects of Organic Additives on Electrochemical Properties of SiOx Electrodes in Lithium Secondary Batteries

Electrochemical reactions occurring at a SiOx electrode were investigated to gain insight about the effects of film-forming additives, such as vinylene carbonate (VC), ethylene sulfite (ES) and 1,3-propane sultone (PS), on the formation of a solid electrolyte interface (SEI) on the SiOx electrode. The SEI formed in the presence of PS was found to have the smallest resistance, resulting in low irreversible capacity and good cycle performance.

Mechanism of action of ethylene sulfite and vinylene carbonate electrolyte additives in LiNi1/3Mn1/3Co1/3O2/graphite pouch cells: electrochemical, GC-MS and XPS analysis

The SEI films formation/composition were dominated by VC resulting in better electrochemical performance of LiNi1/3Mn1/3Co1/3O2 (NMC)/graphite pouch cells.

Conductivity and Dielectric Studies of Lithium Trifluoromethanesulfonate Doped Polyethylene Oxide-Graphene Oxide Blend Based Electrolytes

Series of polymer blend consisting of polyethylene oxide (PEO) and graphene oxide (GO) as co-host polymer were prepared using solution cast method. The most amorphous PEO-GO blend was obtained using 90 wt.% of PEO and 10 wt.% of GO as recorded by X-ray diffraction (XRD). Fourier transform infrared spectroscopy (FTIR) analysis proved the interaction between PEO, GO, lithium trifluoromethanesulfonate (LiCF3SO3), and ethylene sulfite (ES). Incorporation of 25 wt.% LiCF3SO3into the PEO-GO blend increases the conductivity to3.84±0.83×10-6 S cm−1. The conductivity starts to decrease when more than 25 wt.% salt is doped into the polymer blend. The addition of 1 wt.% ES into the polymer electrolyte has increased the conductivity to1.73±0.05×10-5 S cm−1. Dielectric studies show that all the electrolytes obey non-Debye behavior.
