This study proposes a novel multifunctional additive,3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-5-(trifluoromethyl)pyridine (TDBTFP), which helps to restructure the Li⁺ solvation structure, so as to reduce the Li⁺ desolvation energy barrier and improve Li⁺ transport kinetics. The introduction of TDBTFP enables the construction of a solid electrolyte interphase (SEI) enriched with LiF, LiB_xO_y and Li₃N on the Li anode, thereby suppressing dendrite growth. Simultaneously, a cathode electrolyte interphase (CEI) with a gradient composition is formed on the NCM811. The CEI structure features LiF residing predominantly in the inner layer and Li₃N/LiB_xO_y concentrated mainly in the outer layer, which collectively enhances Li⁺ conductivity and inhibits phase transition and transition metals dissolution for the NCM811. Furthermore, TDBTFP acts as an efficient HF scavenger. Consequently, Li||NCM811 battery with TDBTFP-contained electrolyte delivers a high initial discharge capacity of 214.4 mAh g^-1 and retains 88.8 % of its initial capacity after 200 cycles at a high cut-off voltage of 4.6 V, along with 86.5 % retention at 4.7 V and 72.3 % at 60 °C after 200 cycles of its initial capacity respectively.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"87 ","pages":"Article 105033"},"PeriodicalIF":20.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147440216","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}

This review focuses on the critical issues facing typical HCCs, clarifies the influence of ESWs and the electrolyte environment on HCCs, discusses the potential of hybrid electrolytes (containing both aqueous and non-aqueous components, HEs) for enabling new HCCs, and provides insights into improving HCC reliability through electrolyte optimization.

To date, the cathode reaction mechanism of SWBs has been predominantly described by oxygen evolution and reduction reactions (OER/ORR). However, this assumption is valid only under idealized ocean-like conditions with constant pH and continuous oxygen replenishment. In practical systems, SWBs operate in finite volumes of saltwater, where saltwater composition dynamically evolves during cycling. In this work, we systematically investigate the cathode reaction mechanisms of SWBs under finite saltwater conditions using galvanostatic cycling combined with electrochemical diagnostics and <em>operando</em> monitoring of dissolved oxygen and pH. Our results reveal that the cathode chemistry during SWB operation is considerably more complex than previously assumed. In addition to OER and ORR, hypochlorite formation and consumption reactions, along with pH-dependent switching of dominant reaction pathways, play critical roles. We further identify the sequence and relative contributions of these reactions throughout charge–discharge cycling. These findings provide a comprehensive and mechanistically grounded understanding of SWB cathode processes under relatively realistic cell design and operation condition. The insights presented here establish a new framework for interpreting SWB electrochemistry and offer directions for future strategies aimed at improving performance, stability, and practical viability.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"87 ","pages":"Article 105046"},"PeriodicalIF":20.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147464845","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}

Direct regeneration avoids the complete decomposition of SLFP materials, but faces the challenges of severe degradation of surface carbon coatings and repair and regeneration of bulk lattice distortion. We propose a gradient bonding heterostructure construction strategy for efficient direct regeneration of SLFP, achieving triple effects of internal crystal element gradient embedding, interface fast ion conductor hinge, and surface carbon layer activation reconstruction. The process utilizes plasma etching to create an activated carbon layer with exposed active sites. The plasma energy drives Y³⁺ to anchor between the carbon layer and LFP, while enabling the Li⁺ to migrate through the surface activation channels to the bulk phase of LFP. During subsequent calcination, YPO₄ grain boundaries form at the interface, creating a C-O-Y bonding conductive network with the functional carbon layer that enhances electronic conductivity. Simultaneously, the doping of Y³⁺ into the LFP lattice effectively enhances the structural stability of the material. The regenerated LFP delivers a high initial capacity of 151.1 mAh g^-1 at 1 C and demonstrates a capacity retention of nearly 100% after 800 cycles.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"6 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2026-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147383924","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}
