Abstract MXene and MBene, with diverse adjustable surface bulk structures, show many unique chemical properties are applied in various energy storage technologies, the latest developments for them reviewed respectively. However, current reports on synthesis of two materials application related devices still separate limited to macro details. In this review, microscopic chemistry strategies MBene differences caused by structure between elucidated. Later, impact their overall morphologies subsequent material property discussed, key considerations field described. Next, it is elaborated how phases utilize these participate electrochemical reactions individually or synergistically. Unlike previous reviews, incorporated into a unified framework from perspective discussion, relationship synthesis‐structure/properties‐function Finally, “skipping strategy” “joint devices” as next‐generation design concepts fields, development template proposed.

Formation of a stable LiF-rich SEI layer on molybdenum-based MXene electrodes for enhanced lithium metal batteries

Energy Materials, Год журнала: 2025, Номер 5(3)

Опубликована: Янв. 17, 2025

Lithium metal batteries are considered highly promising candidates for the next-generation high-energy storage system. However, growth of lithium dendrites significantly hinders their advance, particularly under high current densities, due to formation unstable solid electrolyte interphase (SEI) layers. In this study, we demonstrate that molybdenum-based MXenes, including Mo2CTx , Mo2TiC2Tx and Mo2Ti2C3Tx form more stable LiF/Li2CO3 SEI layers during plating, compared conventional Cu electrode. Among these, bimetallic MXene, with its higher fluorine terminations, produces most LiF-rich layer. The inorganic layer reduces nucleation overpotential deposition, promotes uniform Li suppresses dendrite growth. Consequently, substrate achieved prolonged cycling stability approximately 544 cycles coulombic efficiency ~99.79% at density 3 mA cm-2 capacity 1 mAh cm-2. full cells, anode, paired an NCM622 cathode, maintained retention 70% over 100 cathode loading 10 mg Our approach highlights potential Mo-based MXenes improve performance batteries, making them energy

Abstract Lithium‐sulfur (Li–S) battery with high capacity and energy density is a promising next‐generation storage device. However, the shuttle effect of polysulfides causes low utilization sulfur side reactions at electrode interface. The electrode/electrolyte interface determines chemical activity electrochemical reversibility as well cycling stability battery. Therefore, ideal in Li–S depends on loading, fast ion diffusion, effective active intermediates, uniform deposition lithium anode. MXene two dimension layer structure, good conductivity, abundant terminal groups can serve carrier to load sulfur, anchor polysulfides, accelerate transfer. This review summarizes three strategies MXene‐based interfaces including host interface, functional separator anode based principles challenges In addition, interfacial regulation application materials focus process are also presented. Finally, further prospective discussed.
