Flexible energy storage devices with high energy density and long lifespan are in great demand for wearable and stretchable electronics. Herein, we report a flexible Zn-ion battery comprised of atomic layer deposited V₂O₅/C cathode, electrodeposited Zn/stainless-steel mesh anode, and para-polybenzimidazole (p-PBI)-based quasi-solid-state electrolyte membrane. The electrochemical and mechanical performances of such a thin-film Zn-ion battery are excellent, exhibiting high and stable reversible capacity with great flexibility over a wide temperature range.
