Rational Design Toward Advanced Non‐Flow Aqueous Zinc‐Bromine Systems Boosted by Alkaline‐Neutral Decoupling Electrolytes

Small Methods, Год журнала: 2024, Номер unknown

Опубликована: Апрель 9, 2024

Abstract Non‐flow aqueous zinc‐bromine batteries (AZBBs) are highly attractive owing to their lightweight construction and largely reduced cost compared with the flow ones. Yet, development is restricted by sluggish reaction kinetics of Br 2 /Br − , shuttle soluble polybromide species (Br n odd), poor stability Zn‐based anode. Herein, an effective alkaline‐neutral electrolyte decoupling system constructed mitigate these issues, where nitrogen‐doped carbon felt high catalytic activity developed for cathode, a cost‐effective cation exchange membrane (CEM) polyethersulfone/sulfonated polyether ether ketone (PES/SPEEK‐M) that can stop used as separator, glucose inhibit dendrites introduced anolyte additive. The flowless AZBB mainly consists two separate redox couples, including Zn/Zn(OH) 4 2− in alkaline neutral media, non‐cations (e.g. OH Zn(OH) H O, ) be respective chamber PES/SPEEK‐M while cations pass by. In optimized system, good electrochemical performance achieved, surprising discharge voltage 2.01 V, average Coulombic efficiency 96.7%, cycling life ≈1000 cycles without obvious capacity decay at fixed charge mAh cm −2 .

Abstract Photorechargeable zinc ion batteries (PZIBs), which can directly harvest and store solar energy, are promising technologies for the development of a renewable energy society. However, incompatibility requirement between narrow band gap wide coverage has raised severe challenges high‐efficiency dual‐functional photocathodes. Herein, half‐metallic vanadium (III) oxide (V 2 O 3 ) was first reported as photocathode PZIBs. Theoretical experimental results revealed its unique photoelectrical storage properties capturing storing energy. To this end, synergistic protective etching strategy developed to construct carbon superstructure‐supported V nanospheres @CSs). The characteristics , combined with three‐dimensional superstructure assembled by ultrathin nanosheets, established rapid charge transfer networks robust framework efficient stable solar‐energy storage. Consequently, @CSs delivered record properties, including photo‐assisted discharge capacities 463 mA ⋅ h g −1 at 2.0 A long‐term cycling stability over 3000 cycles. Notably, PZIBs using photocathodes could be photorecharged without an external circuit, exhibiting high photo conversion efficiency (0.354 %) photorecharge voltage (1.0 V).
