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}

NMC is usually processed using organic solvents that are non‐sustainable. Nevertheless, increasing the Ni fraction entails a decrease in the electrode stability and the processability of this material in water. In this work, high‐nickel NMC materials have been subjected to water processing. In an initial stage, water sensitivity of the materials has been studied. Then, the formulation has been adapted to enhance the NMC fraction without penalizations in the electrochemical performance and compared to an organic solvent‐based formulation. The recipe developed, consisting of 93% of NMC, has been successfully upscaled to a semi‐industrial coating line. The pH buffering has been observed as a critical step to mitigate lithium leaching and implement this process in an industrial environment. The obtained electrodes have been tested in single‐layer pouch cells using silicon‐based negative electrodes, also processable in water‐based slurries. The resulting cells provide limited cycling life due to the low cyclability of the negative electrode but evidence that it is industrially viable to manufacture high‐energy cells consisting only of water‐processed electrodes.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"20 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185146","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}

Alternative cell designs with a planar Na-β''-alumina ceramic electrolyte have been a focus of research for many years, and a series of achievements were made on cell design, on reduction of the operating temperature, and on the analysis of electrochemical reaction mechanisms. However, the data presented in these reports was derived from laboratory-scale cells with small area (1-5 cm2).

Our cell design enabled cycling at 300 °C for three months, transferring a cumulative capacity of 323 Ah.

Our MCE offers a wider electrochemical stability window (2.7 V), low HER activity, and superior Zn anti-corrosion properties due to reduced water activity compared to conventional electrolyte.

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.
