MXenes-based Multifunctional Nanomaterials for Lithium-ion Batteries: Opportunities and Challenges

MXene-based multicomponent materials are 2D substances derived from transition metal (M) with carbide/nitride combinations having several propitious uses, including the fabrication of highperformance electrode materials utilized in Lithium- ion batteries (LIBs), particularly for energy storage devices. The suitability of these new classes of materials for LIB electrodes can be attributed to their high conductivity combined with their excellent surface properties desirable for electrode applications, such as fast charge-discharge capability, high storage capacity and high rate capacity. However, there are several challenges possessed by MXene-based nanomaterials in the application of their electrodes in future flexible and wearable devices, demanding more research work and development strategies. After a brief overview of MXenes used in batteries, this paper deals with the synthesis, morphology-properties correlations, and their performance. Finally, this paper highlights the advantages, limitations, and challenges of MXene-based electrodes for LIBs, ending with concluding remarks.
