two-dimensional niobium and vanadium carbides have been synthesized
by selective etching, at room temperature, of Al from Nb2AlC and V2AlC, respectively. These new matrials are promising
electrode materials for Li-ion batteries, demonstrating good capability
to handle high charge–discharge rates. Reversible capacities
of 170 and 260 mA·h·g–1 at 1 C, and 110
and 125 mA·h·g–1 at 10 C were obtained
for Nb2C and V2C-based electrodes, respectively.
