However, the use of fluorinated salts such as LiPF₆ and LiTFSI in commercial cells raises environmental concerns, leading to increased efforts to develop fluorine-free alternatives. In this study, we present the synthesis of lithium (1-naphthalenesulfonyl)-dicyanomethide (LiNPDM), a novel fluorine-free salt containing a dicyanomethide moiety and a naphthalene group, obtained in three steps from naphthalene sulfonate. For comparison, its trifluoromethanesulfonimide analogue (LiNPTFSI) was also prepared. The electrochemical performance of both salts were studied in conventional liquid electrolyte solvents (EC:DMC) and polycarbonate-based solid polymer electrolytes (SPEs). Although LiNPDM shows a narrower electrochemical stability window, attributed to cyano group oxidation at 4.0 V vs Li⁺/Li, its conductivity performance matched those of its fluorinated analogue LiNPTFSI, both in conventional liquid electrolytes (3.5 mS∙cm^‑1) and SPEs (∼ 1 × 10^‑6 S∙cm^‑1 at 80°C). These results suggest that the dicyanomethide functional group is a promising fluorine-free alternative to the conventional trifluoromethylsulfonimide group.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"32 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamic structure of TCNQ(ACN) and blank ACN modified Pt catalysts, along with their impacts on the performances in FAOR and GOR were analyzed. A strong relationship was established between the performance of FAOR and GOR and the modifier concentration in the reaction solution. ACN exerted a geometric blocking effect on Pt, thereby considerably improving the direct dehydrogenation process of FAOR. Based on ACN, the performance of the dehydrogenation process of FAOR and GOR was further boosted for the surface electron-rich Pt catalyst due to modification with additional TCNQ modifier. Additionally, the resistance to CO poisoning of modified Pt catalyst was notably improved, and the onset potential decreased from 0.656 V of the unmodified Pt to 0.583 V for a specific amount of TCNQ(ACN) modified Pt catalyst.

Ca(BH₄)₂ in tetrahydrofuran (THF) is one of the more widely-tested electrolytes and a current benchmark given its highest-to-date Coulombic efficiency (CE) of Ca plating/stripping. Yet, there is limited understanding of the reactions forming the solid electrolyte interphase (SEI) and the resulting degree of SEI stability, which impedes understanding into this electrolyte's function. To begin to address these knowledge gaps, this study employs gas chromatography (GC) analysis to track gas evolution markers of SEI formation in Ca(BH₄)₂/THF across a range of cell conditions and timescales. In general, both H₂ and linear hydrocarbon (RH) gases are detected as the major evolved gas species, with the former predominantly evolving from reaction between Ca(BH₄)₂ and residual water, and RH products evolving from reaction between Ca and THF. RH evolution is found to be dynamic for cells at rest, with distinct timescales attributed to initial and extended SEI formation and spanning several days. When cells are polarized during Ca plating, RH evolution arrests after a certain plated capacity is reached, signaling the formation of a protective yet functional SEI that continues to be permissive to Ca plating to higher capacities. Yet, this SEI is metastable, as further chemical changes are observed when polarization is relaxed. Given the significant role of water in contributing to H₂ evolution, we further systematically investigate the impact of water on SEI formation dynamics and composition. Increased water content is observed to mainly shorten SEI formation timescales, but its impact diminishes over extended cycling, and the SEI composition ultimately remains largely independent of initial water content. Despite the ability of the Ca plating electrochemistry to tolerate a degree of water in cells, the associated H₂ evolution presents challenges to any practical implementation of this electrolyte.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"22 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
