H2O2 assisted hydrothermal oxidation of partially etched vanadium carbides (MXene) and their electrochemical properties as anode for Li-ion batteries

The novel V2CTx MXenes have gained increasing attention as anode materials in lithium-ion batteries, but to boost their practical to the theoretical values is still challenging. Herein, the partially etched V2CTx was oxidized in the presence of H2O2 through a hydrothermal reaction and the electrochemical properties of as-obtained oxidized V2CTx were assessed. It is illustrated that the oxidized V2CTx possesses a large surface interlayer spacing,...
