MoS2@C with S vacancies vertically anchored on V2C-MXene for efficient lithium and sodium storage

V 2 C-MXene induced abundant S vacancies and modulated the charge distribution of MoS 2 , thereby enhancing the intrinsic conductivity and providing more active sites for ion adsorption. V 2 C-MoS 2 @C displayed excellent electrochemical performance in LIBs and SIBs.
