Application of bis(fluorosulfonyl)imide-based ionic liquid electrolyte to silicon–nickel–carbon composite anode for lithium-ion batteries

Electrochemical lithiation of thin silicon based layers potentiostatically deposited from ionic liquid

“…A preliminary study in this field showed the voltammetric behavior of electrodeposited Si in [BMP][TFSI], emphasizing on the future applicability of electrodeposited thin Si films and the necessity of further research [53]. Furthermore, composite electrodes based on dispersed silicon powders have not been studied in [BMP][TFSI] and their performance in other IL based electrolytes is presented in a limited number of contributions [19,[54][55][56]. It was shown that the cycling performance of Si strongly depends on the ionic liquid type.…”

A New Prospect for Stabilization of Graphite Electrode/Electrolyte Interface in Bis(fluorosulfonyl)imide Anion-based Ionic Liquid Electrolyte

“…[1][2][3] The Li-ion batteries assembled with FSI ¹ -based IL electrolytes show quite good electrode/electrolyte interfacial performance. [4][5][6] However, the control of electrochemical stability of EMImFSIbased IL electrolytes at a graphite electrode/electrolyte interface is quite difficult. The electrochemical instability of EMImFSI-based IL electrolytes at the graphite electrode/electrolyte interface would be attributed to EMIm + insertion into graphene interlayers and its reductive decomposition.…”

Charge-Discharge Characteristics of a LiNi1/3Mn1/3Co1/3O2 Cathode in FSI-based Ionic Liquids

“…12,13 In addition, we have investigated the electrochemical behavior of a high-capacitive Si-C composite anode in an FSI-based ionic liquid electrolyte, in which galvanostatic cycling of the anode in the ionic liquid with a charge limitation of 800 mAh g ¹1 is stable for 50 cycles. 14 Matsumoto et al, 1517 Guerfi et al, 18 and Seki et al 19 also reported the advantages of FSI-based ionic liquids for lithium-metal/lithium-ion batteries.…”
