Integrated All-Flexible Zinc-Ion Battery Based on Leather Gel Electrolyte
Abstract
An integrated all-flexible zinc-ion battery was fabricated. It tightly integrates cathode/anode with quasi-solid leather gel electrolyte, which effectively eliminates mechanical deformation-induced displacement. The battery retains over 97% capacity under 100 bending cycles, perforation, and 6 kg of pressure. It can also power devices under extreme conditions like waterlogging and fire.
