title: New two-dimensional niobium and vanadium carbides as promising materials for Li-ion batteries.
abstract: New 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.
