Rational modulation of emerging MXene materials for zinc‐ion storage

Abstract

Currently, emerging battery technologies are being studied intensively. The lack of ideal electrode materials remains a key hindrance to further development of new batteries. The novel MXene material, due to its unique structural characteristics and physicochemical properties, shows the ability to enhance the electrochemical performance of the electrode. In addition to the adjustable layer spacing, because of excellent electrical conductivity, rich chemical composition, and controllable surface chemistry, MXene has the potential for use in diverse applications as an ideal electrode material in various battery systems. This review covers the recent progress achieved in research of the zinc‐ion energy storage of MXenes, including MXene‐based cathodes, MXene‐derived cathodes, MXene‐modified zinc anodes, and electrolyte additives. Moreover, further structural design and reaction mechanisms of MXenes in zinc‐ion storage are explored.

A stepwise oxidation strategy for the synthesis of amorphous V2O5@V2CTxnanohybrid cathodes toward high-performance aqueous Zn-ion batteries

“…The peaks at 13.5°and 41.5°show a signicant decrease in intensity, indicating the presence of the unetched V 2 AlC MAX phase, which appears in almost all V 2 CT x MXenes synthesized by HF etching. 30,31 Aer oxidation (Fig. 2a), some new peaks appeared that are in good agreement with the M phase of VO 2 (JCPDS No.…”

Recent advances and perspectives for Zn-based batteries: Zn anode and electrolyte

“…Metal Zn has become the most desired anode candidate due to its low toxicity, high abundance, low price ($2 per kg), nonflammability, excellent electrochemical reversibility, stability, and corrosion resistance in aqueous and organic electrolytes. Furthermore, Zn 2+ has been considered the most easily electrodeposited ion in aqueous solutions [29][30][31].…”
