Lithium metal anodes are considered as ultimate replacement for lithium-ion batteries due to their high theoretical capacity and lowest potential as compared to graphite. 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. 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. Ti3C2Tx have attracted intensive attention due to their facile synthesis and high stability. This work provides a modification of Ti3C2Tx synthesis process to improve the charge transfer in electrode. The Ti3C2Tx synthesis process increased the Flourine (-F) content which allows the homogeneous Li metal nucleation due to stable SEI layer.
