While traditional carbon-based materials have been widely used, they face limitations such as low adsorption capacity, weak structural stability, and poor performance in multivalent ion removal, which restrict their practical applications in high-salinity or complex water sources. In contrast, metal sulfides, with their unique structural and electrochemical properties, exhibit higher adsorption performance, stability, and selectivity, especially for heavy metal ions, making them ideal for CDI applications. However, few reviews focused on the adsorption performance, design strategies, and potential challenges of metal sulfides in the CDI field. This paper provides a comprehensive review of the adsorption performance and design strategies for metal sulfides, focusing on interface, defect, surface, and structural engineering to enhance CDI efficiency. It also provides various solutions for addressing critical challenges, including optimizing synthesis, fabricating high-performance materials, understanding ion capture mechanisms, developing versatile ion removing materials, and integrating CDI with complementary technologies. Through these insights, this review aims to guide the development of high-performance metal sulfide-based electrodes, paving the way for more efficient and durable CDI technologies.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"142 ","pages":"Article 111175"},"PeriodicalIF":16.8,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of plasticizers is an effective method to enhance the mechanical properties and output performance of triboelectric nanogenerators (TENGs). However, the development of green plasticizers and investigation of the mechanisms responsible for plasticization and output performance enhancement remain limited. Therefore, in this study, we plasticized chitosan (CS) films using different polyol-based green plasticizers (erythritol, xylitol, and sorbitol) and compared their output and mechanical properties to explore the plasticizing and output performance enhancement mechanisms. Results demonstrate that sorbitol plasticization results in a larger three-dimensional network structure, producing elastomeric materials with stronger deformation ability, which increases the effective contact area and enhances triboelectric output performance. The TENG prepared using sorbitol as the plasticizer (CS–sorbitol-based TENG) exhibits the highest output performance, primarily attributed to its reduced highest occupied molecular orbital–lowest unoccupied molecular orbital energy gap and enhanced electron-donating capacity. In addition, the best strategies for enhancing the output performance of plasticized CS films were identified and applied for respiratory sensing and the complete degradation of a positive friction layer. This study transforms rigid CS into a flexible sensor and provides an environmentally friendly approach for developing high-performance flexible sensors.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"142 ","pages":"Article 111171"},"PeriodicalIF":16.8,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the practical implementation of thin Li anodes is significantly challenged by the inevitable formation of lithium dendrites, as well as the lithium depletion caused by interfacial side reactions. To address this, we propose a lumped Li-Gr@MgF₂ (LGMF) anode comprised of lithiated MgF₂-coated graphite, which precisely reconstructs the lean-lithium metal anode through bottom-up integration. Finely optimized electrode units of LiC₆-LiMg/LiF possess lithiophilic Li-Mg alloy and high-interface-energy LiF interfacial modification, which regulate the lithium-ion flux and effectively suppress dendrite growth. Assembling electrode units collaboratively establishes the ion-electron percolating network within the LGMF, fully activating the entire anode.
