The fundamental properties and representative synthesis methods of MXenes are first introduced, followed by a discussion of their roles as conductive hosts for sulfur, silicon, and selenium active species. Particular emphasis is placed on modification strategies, including surface terminal regulation, heteroatom doping, interlayer spacing engineering, multicomponent compositing, and multi-element co-doping. The applications of MXene-based electrodes in supercapacitors, metal-ion batteries, lithium–sulfur/selenium batteries, and micro energy-storage devices are then discussed with attention to structure–performance relationships.

Herein, a series of Y-F co-doped LNMO materials (LiNi₀.₅₋ₓYₓMn₁.₅O₃.₉₅F₀.₀₅, x = 0, 0.01, 0.03, 0.05) were synthesized via the metal complex polymerization gel (MCPG) method. The synergistic effect of Y-F co-doping on the crystal structure, microstructure, and electrochemical performance was systematically investigated. Through material characterizations including XRD, FTIR, XPS, SEM, EDS, and TEM, a synergistic “dual-directional modulation” mechanism is revealed: Y³⁺ doping expands the lattice parameter and increases Mn³⁺ content, thereby enhancing electronic conductivity; while F⁻ doping forms robust F–Mn bonds that effectively suppress Mn³⁺ disproportionation and dissolution. The results show that LiNi₀.₄₇Y₀.₀₃Mn₁.₅O₃.₉₅F₀.₀₅ (0.03YF) effectively suppresses the formation of LiₓNi₁₋ₓO impurity phase, induces an increase in lattice parameters, enhances cation disorder degree, and raises Mn³⁺ content. Moreover, it promotes the morphological transformation of crystal particles from regular octahedra to truncated octahedra, exposing more highly active {100} crystal facets. Electrochemical test results demonstrate that the 0.03YF sample delivers an initial discharge capacity of 132 mAh/g at 1 C, maintains a high capacity retention of 93.9% after 200 cycles, and still retains 81.8% of its capacity at a high rate of 10 C. The Li⁺ diffusion coefficient calculated from CV measurements reaches 10.55 × 10⁻¹² cm²/s, which is 73% higher than that of the pristine sample. EIS tests show that the charge-transfer resistance (Rct) is substantially reduced from 95.3 Ω to 41.5 Ω, leading to significantly decreased electrode polarization. Y-F co-doping possesses unique advantages in simultaneously optimizing the bulk structure and the electrode/electrolyte interface, offering a promising strategy for advancing the practical application of high-voltage LNMO cathode materials.</p></div>","PeriodicalId":599,"journal":{"name":"Ionics","volume":"32 10","pages":"10627 - 10646"},"PeriodicalIF":3.4,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148962107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve a sustainable upgrading and low energy consumption process, electrochemical refining based on ionic liquid would be a potential strategy, while high cost of ionic liquids has substantially suppressed the industrial progresses. For addressing this issue, here a potential low-cost and low-temperature electrochemical refining of aluminum and aluminum alloys has been demonstrated via employing AlCl₃-CO(NH₂)₂ electrolyte. The optimal cathodes and electrolytes for electrochemical refining are confirmed, allowing for stable electrochemical operation at current density of 30 mA/cm² under temperature of 80℃. The electrochemical refining experiments suggest that such strategy is universal to electrochemical refining different types of aluminum alloys, and the purity of the as-refined aluminum at the cathodes exceeds 99.3wt%.
