Hierarchical intercalation of tetrafluoroborate anion into graphite electrode from sulfolane
文献摘要：
The anion storage behavior of graphite positive electrode in a dual-ion battery is closely related to the solvation of anion in the corresponding electrolyte solution.The classical electrolyte solutions of LiBF4-sulfolane(SL)have long been recognized in the community of lithium batteries and still appear promising in dual-ion batteries.Nevertheless,the solvation of BF4 by SL has seldom been addressed before.In this study,the solvation states of SL-BF4 are adjusted by varying LiBF4 concentration or introducing auxiliary salts of LiPF6 or SBPBF4(SBP:spiro-(1,1')-bipyrrolidinium)in the electrolyte solutions of Li/graphite dual-ion cells.The electrochemical storage processes of SL-BF4 anions in graphite electrodes are investigated through in situ X-ray diffraction measurements.Two kinds of graphite intercalation compounds(GICs)with contrastive intercalation gallery heights(IGHs)have been discovered,which are ascribed to the stor-age of different kinds of SL-BF4 anions in graphite electrode.The interactions between ions and SL in the electrolyte solutions are characterized by Fourier transform infrared spectroscopy and then correlated with the performance of Li/graphite cells.
