Applications of the MXenes in Li-Ion Batteries

Abstract

The design and fabrication of high-performance rechargeable Li-ion batteries (LIBs) can be only done by introducing potential anode materials with superior electrochemical, structural, electronic, and optical properties than the current graphite anodes. To address the challenges of developing Li-ion battery anodes involve huge volume expansion, Li-dendrite growth, Li-ion diffusion kinetics issues, lower conductivity, and limited cyclability. The superior conductivity and mechanical, optical, and electronic properties of the 2D materials (Graphene, Borophene, Metal dichalcogenides, and MXenes) will play vital roles in electrochemical energy storage applications. Among them, MXenes or 2D layered transition metal carbides, nitrides, and carbonitrides possess high conductivity, significant volume-specific capacity, hydrophilicity, and versatile surface properties, making them potential choices as anode materials for high-energy Li-ion batteries. MXene-based pristine and hybrid anodes allow facile Li-ion transport and storage and impede the bane of Li-ion dendrite growth, resulting in high volumetric capacities, rate capabilities, and outstanding cyclability features in LIBs. This chapter discusses the recent developments of MXenes and MXene-composites-based anode materials for high-energy LIBs.
