Integrated Network Cathodes by In Situ Phase Transition Break Diffusion Limitation for Zinc Ion Battery

Small, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

The cathode materials set the limitation of aqueous zinc ion batteries (AZIBs) in capacity and restrict their development. Vanadium-based show unsatisfactory conductivity strong interactions with Zn2+ as well a narrow voltage window. Herein, an integrated network structure is obtained by modulating window to phase transition from VO2 HXV2O5. This has multiple advantages: low crystallinity abundant active sites; good electrolyte wetting; two-electron transfer for high specific capacity. AZIBs exhibit impressive rate performance (545 mAh g-1 at 0.1 A 185 20 g-1) cycling (179 after 15 000 cycles g-1), stable operation even -20 °C (391 1 g-1, 97 10 g-1). have power density energy based on mass material (405 Wh kg-1 74 W 102 11 127 kg-1). pouch-type cell can run over 500 h, maximum 45.5 kg-1. mechanism storage are identified, which conducive promoting development cathodes AZIBs.
