However, achieving all-climate SMBs operating at a wide temperature remains a huge challenge because of the instability of the Na/electrolyte interphases and sluggish reaction kinetics, particularly at ultra-low temperature (−40 °C). Herein, we develop a novel NaF-rich composite sodium anode by impregnating NaF into metallic Na (NaF@Na) for the first time. By this design, NaF-rich SEI can be embedded into the anode homogeneously, which can endow the Na/electrolyte interface a good thermal stability at 60 °C and accelerate the desolvation of Na+-solvent molecular clusters at −40 °C. In light of these collective advancements, the NaF@Na||NVP full cell realized stable all-climate operation from −40 to 60 °C with commercial ester-based electrolyte, displaying a high-capacity retention of 90% after 400 cycles (0.2 C) even at −40 °C together with an outstanding electrochemical performance at 60 °C (106.1 mAh g−1, and 76% capacity retention over 2400 cycles at 10 C), which has rarely been achieved in previous reports. This unique composite Na anode designed offers new insights and prospects for all-climate operating, and lays the basis for practical SMBs later.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"209 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462382","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, typical plasticizers like ionic liquids (ILs) exhibit limitations regarding Zn2+ ion transport and compatibility with the polymer matrix, causing a low Zn2+ transference number (tZn2+) and serious phase separation in SPEs. In this study, we develop a novel fluorinated ILs (F-ILs) plasticizer containing an imidazole cation with a fluoro alkyl substituent as an extended side chain for zinc-based SPEs. This innovative imidazole cation effectively modifies the Zn2+ solvation structure. It significantly enhances the compatibility between ILs and the polymer matrix, enabling fast Zn2+ ion transport (with a notable tZn2+ of 0.46 and high ionic conductivity of 2.8 × 10-3 S cm-1) when incorporated in SPEs. Using the F-ILs-based SPE, we achieve dendrite-free Zn plating/stripping cycling over 2000 h, even at high temperatures. A Zn‖Cl4Q battery assembled with the designed SPE outperforms other solid ZIBs, demonstrating a wide working temperature range (-15 oC to 120 oC) and a long cycling life (capacity retention 70.9% after 2000 cycles at 90 oC). In addition, the pouch cell exhibits a remarkable shelf life (90 days) and a low self-discharge rate (capacity loss of 0.09% per day) at 60 oC, thanks to the high thermal and chemical stability of the SPE during operation. The F-ILs-based SPE, with its advanced ion transport structure, provides solid ZIBs with significant performance improvement, high safety, and enduring durability.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"15 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143452130","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, pinpointing the contributions of individual components of an electrode remains challenging. In contrast, particle-level models based on real microstructures describe active material characteristics but do not accurately reflect performance under cell-level operating conditions. To bridge this modeling gap, we propose a microelectrode modeling framework that considers each component of a composite electrode. This framework enables us to analyze the complex electrochemo-mechanical relationships within the composite electrode. The realistic 3D microstructure of the LiNi0.7Mn0.15Co0.15O2 composite electrode is reconstructed from focused ion beam-scanning electron microscopy images. By applying the intrinsic properties of every component, the composite microelectrode model achieves more than 98% accuracy in terms of the voltage profile compared to the measurement on coin cells. This model allows us to identify three important mechanisms that contribute to the discrepancy between cell and particle levels, i.e., reduced reaction area, increased diffusion length, and insufficient amount of electrolyte. Simulations under an excessive electrolyte condition reveal a significant improvement in rate capability with 94% capacity retention at 4C. In addition, the model considers the role of conductive materials and binders as well as the plasticity of the polymeric binder, enabling the study of degradation mechanisms involving the stability of the binder-particle connection.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"25 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143452129","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, honeycomb shaped Zn dual atom sites embedded in nitrogen doped carbon nanosheets were designed to not only enhance the confinement of I2, but also facilitate the bidirectional redox kinetics of polyiodides through orbital coupling and hybridization, thereby improving the capacity and cycle stability of Zn–I2 batteries. Impressively, the batteries with I2@Zn2NC cathodes received the longest cycle of 100 000 cycles at 50C, retaining an ultra-low capacity fading of 0.0002% per cycle. Additionally, the batteries achieved 7000 cycles at 10C even at −20 °C, verifying good catalytic performance of Zn2NC at low temperature.

Herein, a hybrid quasi-solid-state electrolyte (PHLT) composed of titanium nitride (TiN) fibrous nanofiller and poly(vinylidene fluoride-co-hexafluoropropylene)/lithium bis(trifluoromethanesulfonyl)imide (PVDF-HFP/LiTFSI) matrix was developed.

Further, the in-situ generated fast Li-ion conductor, i.e., LixTiN, derived from lithiated TiN, along with a smooth but dense LiF interphase, effectively bridges the electrolyte|electrode interface and suppresses Li dendrite growth. Consequently, the as-fabricated Li|PHLT|LiFePO4 cells achieve exceptional cycling stability over 3000 cycles at 2 C with superior average Coulombic efficiency of 99.8%.

Herein, a cholesteric structure cellulose nanocrystal (C-CNC) film that leverages the strong coordination interactions between Zn2+ ions and profuse polar functional groups on sulfonate-grafted cellulose chains, was designed as an artificial interphase layer to delicate balance between the sluggish transfer of Zn2+ ions and the faster reduction kinetics, postponing interfacial impoverishment of Zn2+.
