Battery-Type Transition Metal Oxides in Hybrid Supercapacitors: Synthesis and Applications

Batteries, Год журнала: 2025, Номер 11(2), С. 60 - 60

Опубликована: Фев. 5, 2025

Hybrid supercapacitors (HSCs) have garnered growing interest for their ability to combine the high energy storage capability of batteries with rapid charge–discharge characteristics supercapacitors. This review examines evolution HSCs, emphasizing synergistic mechanisms that integrate both Faradaic and non-Faradaic charge processes. Transition metal oxides (TMOs) are highlighted as promising battery-type electrodes owing notable potential compatibility various synthesis routes, including hydro/solvothermal methods, electrospinning, electrodeposition, sol–gel Particular attention is directed toward Ti-, Co-, V-based TMOs, a focus on tailoring properties through morphology control, composite formation, doping enhance electrochemical performance. Overall, discussion underscores HSCs meet demand next-generation systems by bridging gap between power requirements.

Covalent organic frameworks (COFs) have great potential as electrodes for aqueous hybrid supercapacitors (AHCs) owing to their designable structure and resourceful advantages. However, low capacities high instability in electrolytes limit the onward practical applications. Here, we synthesized robust hexaazatrinaphthylene-based COF (HATN-COF) by a simple condensation between cyclohexanehexone 2,3,6,7,10,11-hexaiminotriphenylene. The π-conjugation skeleton, porous structure, high-proportioned imine bonds give HATN-COF sufficient electron ion diffusion pathways rapid reaction kinetics together with abundant exposed active sites large capacity. Meanwhile, formed hydrogen bond networks ethanol molecules improve acid-base tolerance. As consequence, delivers an exceptional specific capacity of 367 mAhg-1 at 1 A g-1 (maximum value among reported COF-related AHCs), rate capability 259.7 20 g-1, superior cycle durability retaining 97.8% its even after 20,000 cycles. Moreover, AHC, constructed positive electrode activated carbon negative electrode, exhibits energy density 67 Wh kg-1 power 375 W kg-1, accompanied outstanding cycling stability. research presents promising approach designing high-performance advanced AHCs.
