Direct regeneration of spent LiFePO<sub>4</sub> is hindered by Li vacancies, Li-Fe anti-site defects, and heterogeneous Fe valences trapped within the olivine lattice. Here we examine defect-to-phase transduction together with carbon-interface reconstruction to address this constraint. Controlled oxidation converts the detectable olivine phase into intermediates containing Li<sub>3</sub>Fe<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> and Fe<sub>2</sub>O<sub>3</sub>, removing the inherited olivine site topology. Lithiation and reduction subsequently reconstruct LiFePO<sub>4</sub> from these intermediates. Rietveld refinement estimates a decrease in Fe-on-Li site occupancy from 5.72% to 0.68%, with a further estimated decrease to 0.35% in the guanidine-assisted sample and a narrower measured electrochemical response. The regenerated cathode delivers 167 mAh g<sup>-1</sup> at 0.1 C and 123 mAh g<sup>-1</sup> at 5 C, retaining 99.2% capacity after 500 cycles at 1 C. Process analysis estimates a profit of US$2.28 kg<sup>-1</sup> of spent cell recycled with lower energy use and greenhouse gas emissions than hydrometallurgical recycling. These results link phase reconstruction and carbon-interface regulation with structural recovery and improved electrode response in spent LiFePO<sub>4</sub>.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"19 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02451-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149339037","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}

However, the capacity degradation law derived from accelerated aging methods is not universally applicable to all operating conditions; thus, lifetime evaluation under calendar aging poses substantial challenges while holding remarkable significance. Herein, comprehensive characterizations were conducted on lithium primary cells subjected to 10-year calendar aging, which aimed to gain a holistic understanding of the degradation mechanism. The results reveal that the surface of the postmortem electrode is covered by complex interfacial species, which exhibit a dual role: They contribute to the low self-discharge rate of cells, and paradoxically, the further deposition of these species at the interfaces between active materials and conductive agents significantly increases the interfacial impedance of electrode, thereby deteriorating the C-rate performance of the cells.

Among various material systems, sulfide solid-state electrolytes (SEs) stand out as highly promising candidates owing to their exceptional ionic conductivity. Nevertheless, their extreme sensitivity to moisture results in the release of toxic H<sub>2</sub>S and rapid structural degradation, which severely impedes their scalable manufacturing under ambient conditions. A bifunctional (3-mercaptopropyl)trimethoxysilane (MPTMS) coating strategy is herein presented to shield Li<sub>5.5</sub>PS<sub>4.5</sub>Cl<sub>0.8</sub>Br<sub>0.7</sub> (LPSCBr) from moisture-induced degradation. The MPTMS layer forms a hydrophobic barrier of approximately 10 nm, which reduces H<sub>2</sub>S emission by 93.0% after 35 min of exposure to 30% relative humidity, while maintaining 83.1% of the initial ionic conductivity (10.8 mS cm<sup>−1</sup>). This approach tackles the core challenge associated with sulfide solid-state electrolytes: the realization of compatibility with controlled ambient air without sacrificing critical electrochemical properties. The modified electrolyte maintains a high ionic conductivity (> 5.7 mS cm<sup>−1</sup>) even after 10 h of air exposure. When applied in all-solid-state cells paired with LiNi<sub>0.83</sub>Co<sub>0.11</sub>Mn<sub>0.06</sub>O<sub>2</sub> cathodes, it exhibits remarkable electrochemical performance, delivering a capacity retention of 84.6% after 1000 cycles.

To meet the demands of next-generation optoelectronic technologies for high performance, low cost, and portability, perovskite materials have emerged as highly promising light-absorbing materials due to their excellent optoelectronic properties, solution processability, and compositional flexibility. Recently, significant performance improvements in perovskite-based PDs have been achieved through various strategies. This review systematically summarizes and analyzes performance enhancement strategies for perovskite PDs. First, the fundamental working mechanisms and key performance parameters of PDs are introduced. Then, four core strategies for performance improvement are discussed in detail. In material preparation, methods for regulating the growth of high-quality light absorption layers are reviewed. In light management, technical approaches such as plasmonic effects, optical microcavities, and nanostructures for enhancing light-harvesting efficiency are summarized. In interface engineering, the impacts of energy level alignment, interface passivation, and charge transport layer optimization on device performance are analyzed. Concerning stability enhancement, the impacts of crystal growth control, additive engineering, and encapsulation technology on device performance are summarized and analyzed. The review further examines the representative applications of perovskite PDs. Finally, key challenges such as stability and large-area fabrication are discussed, along with perspectives on future development. This review aims not only to summarize the performance optimization strategies for perovskite PDs but also to provide a roadmap for their future development and exploration of applications in industrial manufacturing, daily life, and healthcare.</p>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"19 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02335-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149086516","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}
