The preparation of V2CTx by facile hydrothermal-assisted etching processing and its performance in lithium-ion battery

open access: yesJournal of Materials Research and Technology, 2020
In this study, high-purity V2CTx MXene was successfully synthesized by etching V2AlC with fluoride and hydrochloric acid mixed solution using a hydrothermal-assisted method. This method is more concise and effective and has a low level of danger.
