Guided by understanding the crystallization process and inverse materials design principles, we design hard carbon anodes with different local fragments to understand the correlating microstructure of hard carbon and sodium storage behaviors from the commercialization perspective. The sodiation transformation of hard carbon from slope- to plateau-type is realized via a series of local structure rearrangements, including interlayer distance, average crystallite width of graphitic domains, and defect density. We found that the increase in plateau capacity is mainly related to the transition from critical interlayer distance to average crystallite width of graphitic domains control, and is limited by the closed pore volume of hard carbon. During sodiation, the formation of NaF and Na2O in the slope region, as well as Na2O2 and NaO2 in the plateau region, are always accompanied by the production of Na2CO3. This work provides insights into understanding the sodium storage behavior in hard carbon anodes and defines general structural design principles from the slope- to plateau type of hard carbon.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"51 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495801","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, their practical application is hindered by sluggish Zn-ion transfer, parasitic side reactions, and dendrite growth, leading to suboptimal capacity and limited cycle lifespan. Herein, we report a bioinspired design of hierarchical twisted hydrogel electrolytes (HTHEs) by establishing a multi-stage collaborative regulation pathway to address these challenges. The HTHE exhibits a high Zn2+ transference number of 0.9 and a wide electrochemical stability window of 2.61 V, effectively suppressing dendrite formation and enhancing Zn2+ deposition along the Zn (002) plane. Symmetric cells assembled with the HTHE demonstrate exceptional cycling stability across a wide range of current densities, while pouch cells achieve an ultra-long cycle life of nearly 10000 cycles with a high specific capacity of &gt;100 mAh g-1 and 80% capacity retention. Notably, these pouch cells display outstanding flexibility and impact resistance, remaining fully operational under folding and even withstanding extreme mechanical stresses, such as those even crack walnuts. The multi-stage collaborative regulation pathway in the design of high-performance flexible AZIB electrolytes enhances their potential for next-generation energy storage applications.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"85 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495802","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}

System volatility also surges with higher penetration of VRE, represented by increasing variability in hourly marginal demand cost, necessitating firm resources to ensure capacity adequacy. Although these firm sources can earn higher generation revenues in peak hours, capacity compensation amounts to hundreds of yuan/kW (about tens of $/kW) per year is still needed.

However, the practicality of elastic TENGs has been limited by the lack of elastic materials that simultaneously possess the desired mechanical and triboelectric properties. This paper introduces a complementary material synthesis strategy that uses a gradient interpenetrating polymer network (g-IPN) to address this issue. A sub-micron thick g-IPN was formed on a host elastomer (Ecoflex-CNT) that has high contact conformity using a highly chargeable guest polymer (pVP) with a low work function, through initiated chemical vapor deposition (iCVD) process. This complementary material synthesis effectively leveraged only the strengths of each component and resulted in a synergistic enhancement in output performance, with a short-circuit charge density (<em>Q</em><small>_SC</small>) and an open-circuit voltage (<em>V</em><small>_OC</small>) up to 445 μC m<small>^-2</small> and 1335 V, respectively. These values were achieved without affecting bulk mechanical properties of the host elastomer, such as high stretchability and low bulk elastic modulus. Moreover, the depth-directional gradient profile of the g-IPN effectively prevented degradation in output performance under a severely stretched state (up to 100% strain), through a so-called strain-compensating ability. The effectiveness of the g-IPN in three-dimensional (3D)-structured elastic TENGs was successfully demonstrated by applying the g-IPN to a sponge-structured 3D elastic TENG (3D-IPN-TENG), which benefited from the exceptional deposition conformity of the iCVD process. The fabricated 3D-IPN-TENG showed stable operation with a short-circuit volume charge density (<em>Q</em><small>_SC,vol</small>) of up to 267.2 mC m<small>^-3</small>, which is a record-high value among 3D-structured TENGs that utilize contact electrification (CE) between solids.

Here, we present a self-limiting surface leaching mechanism that effectively suppresses continuous leaching, thereby significantly prolonging the lifespan of Ru-based catalysts under acidic OER conditions. Specifically, the Ru–Mn solid solution oxide with a hollow shell structure undergoes surface Mn leaching during the initial OER process, resulting in the formation of a Mn-vacancy-rich stable reconstruction layer. This layer effectively inhibits further leaching of both Ru and Mn, thus self-limiting the further degradation of catalysts.
