Abstract: The properties of 2D layered materials (MXene) and active materials with different sizes, such as zero dimensional (0D), one dimensional (1D) and two dimensional (2D), were reviewed.Preparation and properties of the Ti3C2Tx-based-0D, Ti3C2Tx-based-1D, Ti3C2Tx-based-2D, and other nanomaterials such as Ti3C2Tx-excessive metal oxides, Ti3C2Tx-Fe oxides, and Ti3C2Tx-Co phosphides, were summarized.It is considered that Ti3C2Tx, as an active material, has the function of conducting substrate and even collecting fluid, and its characteristics such as rapid ion or electron transfer channel and structural stability have great potential for application in hybrid electrodes.By synthesizing controllable Ti3C2Tx micro-nano structure and modifying different functional groups on its surface, it is proposed that more active sites can be exposed to improve the ability of ion or electron transfer and structural stability.The degradation reaction of Ti3C2Tx due to the oxygen functional groups on the surface of the Ti3C2Tx should be overcome, which eventually leads to the degradation of the battery performance.Advanced in-situ characterization means can dynamically record various real-time information of electrode and electrolyte during battery charging and discharging, which is convenient to study the formation of SEI film and the volume expansion of electrode material.The key to commercialization of Ti3C2Tx based anode materials is to strengthen the research on the performance of soft-pack batteries.
