Adjustable MXene‐Based Materials in Metal‐Ion Batteries: Progress, Prospects, and Challenges

Abstract

Rechargeable metal‐ion batteries (MIBs) beyond lithium‐ion batteries based on Na, K, Mg, and Al metal electrodes which are earth‐abundant and low‐cost have been developed for large‐scale energy storage systems. MXenes, a type of transition metal carbides, nitrides, and carbonitrides, are discovered as electrodes for MIBs owing to their distinctive properties of large‐scale ultrathin conductive 2D structures, adjustable surface functional groups, regulable interlayer spacing, and high specific surface area. Herein, the properties of MXenes are summarized and the recent progress on MXene‐based materials for diversified MIBs (Li, Na, K, Mg, and Al‐ion batteries) is introduced. The main focus is on the synthesis and applications of MXene‐based materials in MIBs, and their roles in electrochemical reactions. Further examples are provided to demonstrate the significant function of MXene‐based composite as active materials, substrates, collectors, and precursors in different MIBs, highlighting the enormous potential of MXene‐based materials to construct advanced electrodes. This review expects to offer a deep understanding of the relationship between the electrochemical performance and the MXene‐based electrodes, which will promote more novel and creative breakthroughs in the MXenes‐based electrodes for MIBs.

In situ electrochemically activated V2O3@MXene cathode for a super high-rate and long-life Zn-ion battery

“…MXene materials have been widely studied and applied in electrochemical energy storage devices such as supercapacitors, lithium-ion batteries and ZIBs. 16–18 Combining V 2 O 3 with MXenes to obtain a composite of V 2 O 3 @MXene can solve the problem of V 2 O 3 instability. A direct contact between a MXene antioxidant and electrolyte interface can effectively inhibit its dissolution.…”

Advanced Insights on MXenes: Categories, Properties, Synthesis, and Applications in Alkali Metal Ion Batteries

“…At the same time, the increasing number of publications further illustrates the popularity of MXene in batteries (Figure c). We noticed that there have already been several excellent review papers on the application of MXenes for energy storage. − Yet with the tremendous progress and the large amount of works being reported, a timely and comprehensive review of the latest advances and distinctive perspectives of MXenes and their hybrids in emerging rechargeable battery application is needed. In particular, a more comprehensive and systematic summary focusing on the MXene-based materials for AMIBs is essential and beneficial for the researchers exploring high-performance, low-cost, and eco-friendly rechargeable batteries.…”

Advancing lithium–sulfur battery efficiency: utilizing a 2D/2D g-C3N4@MXene heterostructure to enhance sulfur evolution reactions and regulate polysulfides under lean electrolyte conditions

“…31 Additionally, hydroxyl terminal groups on MXenes are anticipated to adsorb LiPSs, initiating redox reactions like the Wackenroder reaction. 32 These reactions connect with long-chain soluble LiPSs, forming poly-thionates and reducing them to insoluble Li 2 S concurrently. These chemisorption and redox processes effectively suppress the shuttle effect of LiPSs, minimizing sulfur loss, and consequently, enhancing the cycling performance of Li–S batteries.…”
