Dendrite-free lithium anode achieved under lean-electrolyte condition through the modification of separators with F-functionalized Ti3C2 nanosheets
文献摘要:
An unstable solid electrolyte interphase(SEI)and chaotic lithium ion flux are key impediments to com-mercial high-energy-density lithium batteries because of the uncontrolled growth of rigid lithium den-drites,which would pierce through the conventional polypropylene(PP)separator,causing short circuit and safety issues.Herein,the homogenization of lithium ion flux and the generation of stable SEI layers on lithium anodes were achieved via coating a fluorine-functionalized Ti3C2(F-Ti3C2)nanosheets on PP separator(F-Ti3C2@PP).F-Ti3C2 nanosheets provide abundant ions pathways to homo-geneously manipulate lithium ion flux and increase the Young's modulus and electrolyte wettability of the separators.In addition,F species derived from the F-Ti3C2 nanosheets would promote the formation of LiF-rich SEI film.The synergistic effect contribute to the uniform lithium deposition.Symmetric Li|Li,asymmetric Li|Cu and full Li|LiFePO4 cells incorporated with the modified separators exhibit improved electrochemical performance even under lean electrolyte conditions.This work provides a feasible strat-egy to improve the performance of lithium batteries through both fluoridized SEI formation and lithium ion flux manipulation.
