MXene has attracted considerable attention as a new type of two-dimensional layered structural materials owing to its high electron conductivity, large specific area, excellent mechanical properties and unique layered structure, which make it promising for application in energy storage, catalysis and adsorption. MXene and its composites have recently aroused intense interest for rechargeable batteries. Transition metal sulfides and oxides have the merits of high capacity, however suffering from issues of low conductivity, relatively large volume expansion and poor capacity retention during cycling. Combining MXene with these materials can not only increase the specific capacity, but also enhance electronic conductivity and solve the volume change during electrochemical cycling, finally achieving superior electrochemical properties. This review covers the key technological developments and latest progress of MXene composites in sodium ion batteries and potassium ion batteries. Starting from a brief introduction of the background of sodium ion batteries, potassium ion batteries and MXene, we mainly focus on research progress on synthesis and application in sodium ion batteries, including sulfides, oxides, and carbonaceous materials. The study on potassium ion batteries is still in its infancy. Current status of MXene and its composite in potassium ion batteries have also been summarized, also current challenges and future perspectives in the application of MXene materials are discussed.
