Lithium metal anodes are considered as ultimate replacement for lithium-ion batteries due to its high theoretical capacity and lowest potential as compared to graphene. However, the dendrite formation during Li metal plating/stripping process hindered the practical application of li-metal batteries. Moreover, dendrite formation becomes more vigorous at high current densities. This uncontrollable dendrite growth leads to capacity loss and insufficient coulombic efficiency. MXene is considered as appropriate lithophilic substrates for Li metal anodes due to its 2D nanostructure, high specific surface area, high electrical conductivity, and numerous functional groups. Especially, Bimetallic MXene are proposed as optimal candidate for high-rate Li metal anodes using titanium niobium carbide (TiNbC) as an example. This work provides a modification of TiNbC synthesis process to improve the charge transfer in electrode.
