A Mini-Review: MXene composites for Sodium/Potassium-Ion Batteries
MXene, as a new type of two-dimensional layered structure material, has attracted much attention. MXene has high electronic conductivity, large specific area, excellent mechanical properties and unique layered structure, which has been extensively used in energy storage, adsorption, catalysis and other fields. In recent years, Mxene and its composite materials have been widely used in the field of secondary batteries.Although Oxides, sulfides and other materials have high capacity, there are problems such as low conductivity, volume expansion in the reaction process, poor cycle stability, etc. Therefore, building composite materials with MXene can not only improve the capacity but also enhance the electronic conductivity of the materials, effectively alleviate the volume expansion in the reaction process, and achieve better electrochemical performance. This article reviews the latest research status of MXene, the synthesis methods, properties and application of MXene and its composite materials in sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs), briefly introduces the research background of SIBs, PIBs and MXene, and focuses on the application research of MXene composite materials in SIBs and PIBs, including classification according to sulfide, oxide and carbon materials. Finally, the development and application prospects of MXene and its composite materials are summarized.
