Nevertheless, their poor compatibility with salts and commonly used solvents leads to the formation of a heterogeneous system, which drastically limits their concentration in the electrolyte and consequently deteriorates the safety performance. In this work, we employ a bridging solvent diethyl carbonate to raise the solubility of a highly effective FRS, ethoxy pentafluorocyclotriphosphonitrile (PFPN), to a concentration as high as 75 vol % in the electrolyte. The target electrolyte forms a stable N/P-rich cathode–electrolyte interface to protect the electrode from oxygen evolution and transition-metal ion dissolution, thereby enabling the LiCoO2 cathode to preserve 72% capacity retention over 500 cycles at 4.62 V. Moreover, this electrolyte can effectively delay occurrence time and improve the critical temperature of thermal runaway of 1 Ah LiCoO2||graphite pouch cells. Our work proposes a new direction for nonflammable electrolytes toward safe and high-energy LIBs.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"9 11","pages":"5364–5372 5364–5372"},"PeriodicalIF":19.3,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142608503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the undesired inactive phase arises from multiple crystal nucleation pathways formed by various intermediate phases during the film formation process, persistently accompanying it. FA-based perovskites frequently struggle to form uniform, highly crystalline films. This challenge complicates the development of reliable and highly reproducible crystallization processes for perovskites and the establishment of guidelines for controlling the α-phase formation. In this work, we investigate the role of poly(acrylonitril-co-methyl acrylate) (PAM) to simultaneously control nucleation and subsequent α-phase crystallization. This successfully demonstrates the regulation of oriented crystal growth through the creation of a PAM-PbI2 intermediate. Ultimately, PAM-modified p–i–n architecture devices obtain a promising power conversion efficiency (PCE) of 25.30%, with VOC (1.211 V), achieving 95% of the detailed balance limit. Additionally, PAM-modified devices maintain ≥90% of the initial efficiency for 1000 h under 1 sun and 65 °C operation.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"9 11","pages":"5434–5443 5434–5443"},"PeriodicalIF":19.3,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142608489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A promising route for overcoming these problems involves coating the Zn anode with eutectic gallium indium (EGaIn)-based liquid metal (LM) with a strong Zn affinity and growth direction tenability. Despite considerable research on EGaIn-coated Zn anodes for ZIBs, this topic has not been comprehensively reviewed. Hence, this Review introduces the application of LMs to ZIBs and particularly discusses the mitigation of stability issues using LM and the fundamental processes related to Zn anodes.

To this end, we herein customize a localized SSE (LSSE) featuring a low ratio of salt-to-solvent and diluent-to-solvent through alkyl chain tuning. A multimodal 2D nuclear magnetic resonance technique is developed to unveil the Li-ion solvation sheath reorganization, which is crucial for studying the coordination and dynamics in liquid electrolytes. LSSE affords an anion-derived solid electrolyte interface and effective restriction of the shuttling effect; hence, our Li–S batteries can sustain a steady operation under 4 μL mgS–1 and 3 mg cm–2.
