In this work, the polymethacrylate-<em>N</em>-dibenzenesulfonimide ester (PM-NDIE) is proposed to penetrate into the interstices of primary particles of LiNi_0.85Co_0.1Mn_0.05O₂. During in-situ polymerization, nucleophilic oxygen and electrophilic sulfur atoms chemically bond with undercoordinated Ni and oxygen on the surface, respectively, modulating the electronic surface state. The <em>in-situ</em> XRD/XAFS/TEM analyses and DFT calculations corroborate that PM-NDIE contributes to slowing down the covalency increase of TM-O bond and preserving atomic coordination integrity even under highly delithiated state, thereby maintaining the integral layered structure during cycling. NCM with the PM-NDIE-engineered surface (P-NCM) demonstrates a distinct thinner inorganics-dominant cathode/electrolyte interphase and enables exceptional interfacial stability. P-NCM delivers a 47% reduction in voltage decay in self-discharge test at 55°C, a 27.4% improvement in capacity retention over 100 cycles at 1C/55°C, and maintains 93.66% capacity after 400 cycles under 1C in Ah-level pouch-cell. Moreover, a significantly inhibited thermal-induced phase transition and a delayed thermal runaway critical temperature of pouch-cells provide further evidence that a major driving force for heat-/oxygen- release spontaneous reaction of NCM has been cut off by stabilizing its electronic surface state.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"58 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083400","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}

The utilization of SSEs in lithium metal batteries (LMBs) is widely recognized as a crucial step in designing next-generation high-performance energy storage devices. Nitrile-based solid polymer electrolytes (SPEs), exemplified by polyacrylonitrile (PAN), have gained prominence due to their exceptional mechanical strength, effective lithium salt dissociation capabilities and excellent interfacial contact. Exploration and modification of intrinsic active functional groups of polymers are emerging as pivotal strategies for advanced SSBs, simultaneously providing foundational framework for analyzing the intricate relationship between microscopic mechanisms and macroscopic performance. This review initially focuses on the dissociation-coupling of ion behavior, kinetics, and various types of nitrile-based polymers. Specifically, focusing on the advantages of nitrile-containing functional groups, the key limiting factors and empirical formula ions transport in SSEs and are summarized. In addition, a brief introduction of numerous achievements related to the diverse applications of nitrile-based organic compounds in SSEs and electrolyte additives with a detailed exposition of current mainstream modification strategies are highlighted, designed to provide direction for optimization and development of nitrile-based SPEs.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"30 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067463","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, solvated water easily induces HER to deteriorate Zn anode interface and has poor performance at low temperatures. Here, formamide (FA) and D-xylose (DX) synergically induce a molecular crowding effect that increases Zn²⁺ kinetics and decreases the freezing point. FA as a ‘chain’ is mainly used to regulate the solvation structure of Zn²⁺ and DX as a ‘bridge’ is mainly used to destroy the hydrogen bond network of water. Therefore, the multiple Zn²⁺ solvation configurations present in FD can effectively inhibit the side reactions and reduce its freezing point to -51 °C. The Zn∣∣Zn battery can operate for more than 3000 h at -35 °C (0.5 mA cm^-2). The average CE of Zn∣∣Cu battery after 3000 cycles is close to 100 %. The capacity retention rate of Zn∣∣PANI battery is 80 % after 3000 cycles at 30 °C (3 A g^-1) and 91 % after 750 cycles at -35 °C (0.1 A g^-1).
