Revealing the formation and electrochemical properties of bis(trifluoromethanesulfonyl) imide intercalated graphite with first-principles calculations
Chol-Jun Yu, Un-Song Ri, Gum-Chol Ri +1
Graphite has been reported to have anion as well as cation intercalation capacities as both cathode and anode host materials for the dual ion battery. In this work, we study the in…

Ab initio study of sodium cointercalation with diglyme molecule into graphite
Chol-Jun Yu, Song-Bok Ri, Song-Hyok Choe +3
The cointercalation of sodium with the solvent organic molecule into graphite can resolve difficulty of forming the stage-I Na-graphite intercalation compound, which is a predomina…
