However, the novel bimetallic ternary metal sulfides suffer from rapid loss of their specific capacitance and poor cycle life because their electrochemical reactions involve multiple redox steps, volume expansion, and irreversible structural changes. Thus, understanding the failure mechanisms in terms of the material chemistry is important for designing novel energy materials with high electrochemical stability during long‐term cycling. In this study, yolk–shell ZnCo2S4 (ZCS) nanoparticles are synthesized and modified with either a carbon shell (ZCS@C) or a polypyrrole (PPy) coating (ZCS@PPy) to explore the failure mechanism of yolk–shell ZCS nanoparticles via the decomposition of their shells. The optimal ZCS@C addresses these issues, producing high capacitance (171 F g−1 at 2 A g−1) with high retention (78% after 5,000 cycles). Therefore, we comprehensively report this investigation on the effects of the physical chemistry and electrochemistry of ZCS materials on the performance of electrochemical supercapacitors, aiming to design ZCS@C electrochemical materials that effectively address the proposed failure mechanisms.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"7 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose a type of SiO2‐based soggy‐sand electrolyte (ZnSO4+MnSO4 electrolyte with SiO2, SiO2‐ZMSO4) and focus on the effect of the SiO2 nanoparticle size on the performance of soggy‐sand electrolyte. It is found that SiO2 with smaller nanoparticle size provides higher porosity, and the SiO2 network‐formed can effectively trap the free water in the electrolyte, which increases the ionic conductivity of electrolyte, widens working voltage window, and decreases the internal resistance of batteries. As a result, the Zn//MnO2 batteries with 20 nm SiO2‐based soggy‐sand electrolyte show stable cycling performance and rate capacities. The specific capacity of the battery can be maintained at 198.5 mAh g‐1 after 1200 cycles at 1A g‐1 without capacity degradation. The specific capacity can be increased by 100 mAh g‐1 even at a high rate of 5 A g‐1.
