Herein, we develop a fluorine and carbonate regulated nonflammable polymer electrolyte (F-HV) for high-voltage Li metal batteries. Fluorinated main chains endow F-HV with high oxidative stability (4.9 V vs. Li⁺/Li) and promote the formation of robust LiF-rich interfaces, effectively enhancing the interfacial stability of LiNi_0.8Co_0.1Mn_0.1O₂ (NCM811) cathodes and Li metal anodes. Carbonate side chains facilitate dissociation and conduction of Li⁺, effectively enhancing the ionic conductivity to 1.97 mS cm⁻¹. F-HV possesses excellent flame resistance and favorable dimension stability up to 200 °C. F-HV markedly boosts the performance of Li||NCM811 and Li||LiFePO₄ (LFP) cells, which exhibit an ultralong cycle life of 3000 cycles with an impressive capacity retention of 86.3%.

Here, we demonstrate that Li-foils with varying thicknesses possess distinct surface finishes and bulk-phase textures. As the extrusion-produced 200 μm Li foils are rich in inorganic surface species and (110)-texture, the 20 μm Li produced via rolling feature organic surface species and (100)-Li texture underneath.

However, limited research has been conducted on how calendar aging influences subsequent cycling performance. This study addresses the gap by examining the effects of state-of-charge (SoC) during short-term low-temperature storage on both calendar aging and cycling degradation in LIBs with high-nickel cathodes. The findings demonstrate that high SoC storage accelerates calendar aging by causing structural degradation at the cathode-electrolyte interface (CEI), leading to phase transitions and increased mechanical stress. However, these conditions also enhance cycling stability by promoting surface reconstruction of the high-nickel cathode, which reduces lattice strain and mitigates detrimental phase transformations. The surface reconstruction improves lithium-ion diffusion and stabilizes the crystal structure, resulting in less mechanical degradation during cycling. Conversely, low SoC storage leads to reduced structural degradation during calendar aging, but the lack of an inert protective layer on the cathode surface causes lattice strain and phase transitions during lithium intercalation, resulting in microcracks that compromise the cathode structure. Concurrently, transition metal dissolution, migration, and deposition accelerate anode degradation by promoting interfacial reactions, which exacerbate solid electrolyte interphase (SEI) formation and degradation, and consume reversible lithium ions. Storage is a critical process in the lifecycle of LIBs in electric vehicles (EVs), necessitating the development of advanced battery management strategies tailored to the SoC-dependent stabilities of active materials. These results emphasize the complex relationship between calendar and cycling aging, providing important insights into optimizing high-energy-density cathodes with long durability.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"76 ","pages":"Article 104143"},"PeriodicalIF":18.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477705","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}

Herein, a novel protonated diatomaceous earth (DE-ALK)-based artificial interphase is fabricated through a scalable tape-casting strategy. Such protective mechanism not only comes from the physical characteristics but also from the unique protonation interface effect of DE-ALK. As demonstrated, through a strong protonation reaction, the surface charge of DE-ALK shifts from negative to positive of +23.37 mV, result in effectively regulating the anode microenvironment. Benefited from the built-in electrostatic field, the side reactions involving anionic species and HER are suppressed by immobilizing sulfate anions, and the de-solvation of hydrated zinc ions is promoted by weakening the interaction between Zn²⁺ and water, thereby accelerating the reaction kinetics and inhibiting the dendrite growth.
