These distinctive characteristics render HEMs highly suitable for various battery components, such as electrodes, electrolytes, and catalysts. This review systematically examines recent advances in the application of HEMs for energy storage, beginning with fundamental concepts, historical development, and key definitions. Three principal categories of HEMs, namely high-entropy alloys, high-entropy oxides, and high-entropy MXenes, are analyzed with a focus on electrochemical performance metrics such as specific capacity, energy density, cycling stability, and rate capability. The underlying mechanisms by which these materials enhance battery performance are elucidated in the discussion. Furthermore, the pivotal role of machine learning in accelerating the discovery and optimization of novel high-entropy battery materials is highlighted. The review concludes by outlining future research directions and potential breakthroughs in HEM-based battery technologies.","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"29 1","pages":"1"},"PeriodicalIF":26.6,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144645984","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 effect depends on the anchoring mode and strength of the interfacial molecules, which determines whether long-term robust interface for carrier viaduct can be achieved under operational light illumination. Herein, we select squaric acid (SA) as the interfacial molecule between the perovskite and SnO<sub>2</sub> layer and propose a self-regulated bilateral anchoring strategy. The unique four-membered ring conjugated structure and dicarboxylic acid groups facilitate stable hydrogen bonds and coordination bonds at both SnO<sub>2</sub>/SA and SA/PbI<sub>2</sub> interfaces. The self-transforming property of SA enables the dynamic bilateral anchoring at the buried interface, ultimately releasing residual stress and constructing a stable interfacial molecular bridge. The results show that SA molecular bridge not only can effectively inhibit the generation of diverse charged defects but also serves as an effective electron transport pathway, resulting in improved power conversion efficiency (PCE) from 23.19 to 25.50% and excellent stability at the maximum power point. Additionally, the PCEs of the flexible and large-area (1 cm<sup>2</sup>) devices were increased to 24.92% and 24.01%, respectively, demonstrating the universal applicability of the bilateral anchoring to PSCs based on different substrates and larger area.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"17 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-025-01846-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nonswelling behavior of nanocolloidal hydrogels takes origin in the resistance to swelling of their hydrophobic regions which are resulted from the nanophase of hydrophobic methacryloyl groups in the interior of the constituent nanoparticles.

However, their practical application is hindered by several challenges, including dendrite formation, corrosion, and the competing hydrogen evolution reaction. To address these issues, we designed and fabricated a composite protective layer for Zn anodes by integrating carbon nanotubes (CNTs) with chitosan through a simple and scalable scraping process. The CNTs ensure uniform electric field distribution due to their high electrical conductivity, while protonated chitosan regulates ion transport and suppresses dendrite formation at the anode interface. The chitosan/CNTs composite layer also facilitates smooth Zn<sup>2+</sup> deposition, enhancing the stability and reversibility of the Zn anode. As a result, the chitosan/CNTs @ Zn anode demonstrates exceptional cycling stability, achieving over 3000 h of plating/stripping with minimal degradation. When paired with a V<sub>2</sub>O<sub>5</sub> cathode, the composite-protected anode significantly improves the cycle stability and energy density of the full cell. Techno-economic analysis confirms that batteries incorporating the chitosan/CNTs protective layer outperform those with bare Zn anodes in terms of energy density and overall performance under optimized conditions. This work provides a scalable and sustainable strategy to overcome the critical challenges of aqueous Zn-metal batteries, paving the way for their practical application in next-generation energy storage systems.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"17 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-025-01837-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
