It is highly crucial to design appropriate battery-type electrode materials for HSs to deliver both high capacity and fast charge-discharge performance. We report the facile route and rapid preparation technique of bimetallic oxide Ni3O6/Co3O4 (CNO) nanocomposite with a unique donut-like morphology by simple one-step wet chemical methods. Further, the donut-like morphology was fine-tuned by changing the urea concentration of 5 mmol (CNO-1), 10 mmol (CNO-2), and 20 mmol (CNO-3) without compromising the hexagonal (Ni3O6)/cubic (Co3O4) crystal structure of all samples. Moreover, the three-electrode measurements exhibit specific capacitances of 219, 284, and 231 F g−1 at 0.5 A g−1 for CNO-1, CNO-2, and CNO-3, respectively. Furthermore, a HS device delivers a specific capacitance of 120 F g−1 at 1 A g−1, along with an energy density of 47 W h kg−1 and a power density of 8500 W kg−1. It maintains 72% capacitance retention and excellent coulombic efficiency of 99% up to 5000 cycles, signifying stable long-term performance. Hence, this work demonstrates an effective and scalable strategy for tailoring the morphology of bimetallic oxide nanocomposites for advanced aqueous HSs.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 3","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147567155","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}

Currently, nonaqueous SSFBs pose safety risks due to the flammability of organic electrolytes, while aqueous SSFBs impede the attainment of high-voltage owing to the limited electrochemical stability window. In this study, a novel SSFB employing the bisolvent-in-salt (BSiS) electrolyte is innovatively developed. LiMn2O4 (LMO) and selenium (Se) are adopted as catholyte and anolyte active materials respectively in the 10 M LiTFSI BSiS electrolyte (H2O:1,3-dioxolane (DOL) = 1:1, BSiS-DOL0.5) to demonstrate this concept. The BSiS-DOL0.5 SSFB exhibits superior safety and low temperature performance as evidenced by the evaluation of flame retardancy and low temperature resistance. The proposed SSFB can operate at ~1.8 V, exhibiting an average capacity degradation rate of only 0.37% and a Coulombic efficiency of 93% over 100 cycles, alongside an energy density of 144 Wh L−1. Finally, the continuous-flow mode test is conducted to verify the feasibility of Se/LMO BSiS SSFBs for over 210 h. This study illustrates the application conditions of BSiS electrolytes in SSFBs and reveals the formation mechanism of active material-electrolyte interface, which provides a significant pathway for the design of novel high-safety and high-energy SSFBs.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 3","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147567112","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}

Synthesized via electrospinning, stabilization, carbonization, and CO2 activation, the freestanding electrodes were characterized by cyclic voltammetry, galvanostatic charge–discharge (GCD), electrochemical impedance spectroscopy, and cycling stability tests, as well as physical and chemical characterizations. The results show promising performance, with the PAN/PMMA/PCBM electrodes achieving an energy density of up to 89.2 Wh/kg and a specific capacitance of up to 209 F/g at a current density of 1 A/g in GCD experiments.
