Carbon-wrapped vanadium dioxide for aqueous zinc batteries based on in situ carbon-impregnation engineering†

Herein, the straightforward in situ carbon-impregnation technique is designed to improve the performance of VO₂@C materials by effectively preventing vanadium ion dissolution as well as enhancing both electronic conductivity and structural stability of the cathodes. Therefore, the VO₂@C composite demonstrates exceptional electrochemical performance.
