As the precursor of MXenes (2D transition metal carbides, carbon nitrides and nitrides), MAX phase materials have attracted ever-increasing attention in electrochemical applications. In this work, we have successfully hybridized a MAX phase, Ti 2 SnC, with various ratios of carbon nanofibers (CNFs) via electrospinning. The results show that the Ti 2 SnC/CNFs compounds possess a stable lithium ion storage ability as an anode material, reaching a stable specific capacity of up to 367.5 mAh·g−1 after 500 charge/discharge cycles at the current density of 1.0 A g−1, which are drastically better than some other MAX phase materials such as Ti 3 SiC 2 and Nb 2 SnC. This strategy provides a new pathway for the improvement of the electrochemical stability of MAX phase, which has a wide application prospect. • Ti 2 SnC/CNFs was successfully prepared by an electrospinning method. • CNFs retard the volume expansion of Ti 2 SnC during the charge/discharge process. • Ti 2 SnC/CNFs performed stable lithium ion capacitance (367.5 mAh·g−1 at 1.0 A g−1).
