Publikováno v: Electrochimica Acta. 303:49-55

We report here a carbonate-free electrolyte for lithium-ion batteries with low flammability which consist of lithium bis(fluorosulfonyl)imide (LiFSI) and 2-methylglutaronitrile (MGN) (LiFSI/MGN). LiFSI/MGN enables reversible lithium ion intercalation

Electrochemical performance of an ethylene carbonate-free electrolyte based on lithium bis(fluorosulfonyl)imide and sulfolane

Autor: Yasutaka Sumida, Kazuhisa Hirata, Yoshihiro Morita, Takeo Kawase

Publikováno v: Journal of Power Sources. 395:163-170

Lithium bis(fluorosulfonyl)imide (LiFSI) is one of the most promising lithium salts for use in lithium-ion batteries owing to its high ionic conductivity, high solubility in organic solvents, and excellent solid electrolyte interphase (SEI)-forming a

Electrode/Electrolyte Interface Study of LiCoO2/Graphite Cell Using Carbonate-Free Electrolytes Based on Lithium Bis(fluorosulfonyl)imide and Sulfolane

Autor: Takeo Kawase, Yasutaka Sumida, Kazuhisa Hirata

Publikováno v: Journal of The Electrochemical Society. 167:020518

LiCoO2/graphite full-cells with a carbonate-free electrolyte based on lithium bis(fluorosulfonyl)imide and sulfolane (LiFSI/SL) show excellent cycle stability at high temperatures. In this study, we used X-ray photoelectron spectroscopy to investigat
