However, issues such as uneven zinc stripping and dendrite growth significantly reduce the cycling life and safety of the battery. To address this, this study proposes a novel zinc anode construction strategy based on a graphite paper substrate, which significantly improves the reversibility of zinc deposition/stripping by regulating the distribution of the interfacial electric field. Compared to traditional copper foil-based substrates (Cu foil@Zn), the zinc deposition layer formed on the graphite paper substrate exhibits a more uniform morphology and superior electrochemical performance. Experimental results show that the Gr paper@Zn anode surface presents a brighter metallic luster, with a mass reduction of approximately 16% compared to the Cu foil@Zn. SEM and XRD analyses confirm that the graphite paper substrate promotes the formation of a uniform and dense Zn (002) crystal face orientation deposition layer, while the Cu foil substrate forms a columnar crystal structure with Zn (101) orientation. Furthermore, the Zn||I2 full battery assembled with Gr paper@Zn retains 75.1% of its initial capacity after 10 000 cycles at a high current rate of 10 C. The Zn||I2 large-area pouch battery maintains 81.2% of its capacity after 800 cycles at a current of 0.8 A. More importantly, the assembled Zn||I2 multilayer pouch battery delivers an Ah-level capacity (1.67 Ah) and maintains 89.9% of its capacity after 100 cycles.

Herein, we report a multifunctional interlayer comprising Mo2C nanoparticles confined within a nitrogen- and phosphorus-codoped amorphous carbon matrix supported on reduced graphene oxide (MNPG). H3PMo12O40 was chosen as a final polyoxometalate (POM) precursor because it was transformed into the tubular nanoparticles, while Na3PMo12O40 was converted to irregular micrometer-sized particles. In particular, the hierarchical structure of MNPG is synthesized via electrostatic self-assembly of POM and pyrrole on graphene oxide, followed by thermal transformation. The embedded Mo2C domains act as efficient redox mediators that accelerate LiPS conversion, while the polar doped carbon shell suppresses parasitic reactions and facilitates ion transport. Consequently, the MNPG-coated separator allows LSBs to deliver a high specific capacity of 1549 mAh g−1 at 0.1 C and 802 mAh g−1 at 5.0 C, along with 81.1% capacity retention after 200 cycles.

This has spurred significant research into recycling spent batteries to enhance resource circulation. Currently, commercially applied recycling methods (such as pyrometallurgy and hydrometallurgy) face environmental and economic challenges, including waste acid and gas generation, high-temperature heat treatment, and operational complexity. A promising alternative is the carbothermic reduction process, which operates at lower temperatures, minimizing costs and environmental emissions. However, this method still requires large quantities of external reducing agents. Therefore, this study aims to introduce a simplified direct carbothermic reduction (SDCR) process. The SDCR process leveraged carbon conductive materials and organic binders within the electrode as reducing agents. Additionally, the high compaction state created a conducive environment for reducing gases, promoting efficient reduction and material recovery. This approach reduces the reliance on external reducing agents and streamlines the re-upcycling process, making it commercially viable.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"9 2","pages":""},"PeriodicalIF":14.1,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70037","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147567354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the Zn anode shows severity of dendrite growth and hydrogen evolution reaction (HER). Addressing these challenges requires effective manipulation of the inner Helmholtz plane (IHP). Thereby, we secure a novel strategy for generating water-locking IHP through the in-situ growth of a hygroscopic Zn-ethanolamine (Zn-EA) protective layer on the Zn surface. This layer forms via coordination between ZnCl2 salt and ethanolamine, effectively reducing the intermediate/free water. Moreover, ethanolamine contains zincophilic sites (C–O and –NH2) further promote the uniform Zn deposition. The in-situ Raman confirms the ability of the hygroscopic layer to lock the active water away from the Zn surface. Therefore, Zn-EA@Zn anode exhibits an impressive life stability of 288 h at 20 mA cm−2 and 20 mAh cm−2 with an extended lifespan of 2100 h at 1 mA cm−2 and 1 mAh cm−2.

In this regard, salt anions have a decisive role in the overall SPE performance. While lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) was chosen earlier to have a highly flexible sulfonimide center and an extensively delocalized negative charge, it still suffers from several drawbacks ascribed to its poor interfacial compatibility with the lithium metal (LiM) anode and the fact that it is a PFAS. In this work, a novel lithium salt is cunningly designed, aiming to combine the advantages of previously reported lithium bis(fluorosulfonyl)imide (LiFSI) and lithium bis(difluoromethanesulfonyl)imide (LiDFSI) to overcome the limitations of the state-of-the-art SPE based on LiTFSI/poly(ethylene oxide) (PEO). The SPE containing the developed (difluoromethanesulfonyl)(fluorosulfonyl)imide (LiDFFSI) salt presented reduced interfacial resistance and improved compatibility with the lithium metal (LiM) anode compared with LiTFSI/PEO, enabled by the formation of a stable, uniform, and ionically conductive solid–electrolyte interphase (SEI). In addition, LiDFFSI-based SPEs demonstrated a prolonged cycling stability, achieving over 125 cycles at C/10 with minimal capacity fading in LiM||LiFePO4 cell configuration. These findings evidence how a rational design of the lithium salt chemistry allows tuning the formed SEI, directly impacting the overall SPE performance.

Experimental results demonstrated the remarkable versatility of gallium vanadium oxide. The free-standing electrode based on gallium vanadium oxide mixed-oxide materials achieved impressive discharge capacities of 571 mAh g−1 for lithium-ion batteries and 202 mAh g−1 for sodium-ion batteries at a 1 C-rate. These values are close to the theoretical capacities of 588 mAh g−1 for lithium-ion batteries and 236 mAh g−1 for sodium-ion batteries, indicating the high efficiency and performance of the gallium vanadium oxide free-standing electrode. The hybrid-ion capacitors further showcased gallium vanadium oxide's capabilities, with lithium-ion capacitors delivering energy and power densities of 178.24 Wh kg−1 and 16.6 kW kg−1, respectively, and sodium-ion capacitors achieving 130.74 Wh kg−1 and 13.30 kW kg−1.

This review article defines ultra-high nickel oxides with a nickel content of ≥0.9 among transition metal components and proceeds based on this definition. Although high-nickel oxide cathode materials have undergone decades of development, the pursuit of increased capacity in ultra-high nickel oxides inevitably leads to compromised capacity retention, thermal stability, and unavoidable structural degradation, thereby hindering their progression. The review article focuses on summarizing the main challenges currently faced by ultra-high nickel oxides as cathode materials for lithium-ion batteries and as well as the mainstream modification measures. Finally, it is pointed out that the future research on ultra-high nickel oxides should focus on high-entropy modification, adaptation to extreme conditions, and the exploration of new preparation and modification methods. At the same time, efforts should be grounded in practical considerations and guided by target performance, aiming to improve various aspects of material performance for different application fields without compromising the high capacity inherent to ultra-high nickel oxide cathodes.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"9 2","pages":""},"PeriodicalIF":14.1,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70160","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147570144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
