▎ 摘  要

NOVELTY - The battery has a sol-gel converting electrolyte coated on a surface of a flexible electrode and leading out the flexible electrode to form a package layer. A component of the sol-sol conversion electrolyte is provided with a zinc salt solution, a pluronic polymer framework and an alpha-cyclodextrin. The pluronic acid powder is used for effectively increasing solubility of the pluronic polymer framework to different zinc salts. The sol-gel transition temperature of the electrolyte containing different zinc salt concentrations is reduced. The graphene conductive ink is used as a carbon-based current collector. USE - The dynamic self-repairing aqueous rechargeable flexible zinc ion battery based on sol-gel converting electrolyte, is useful in wear-resistant and portable electronic technology. ADVANTAGE - The dynamic self-repairing aqueous rechargeable flexible zinc ion battery has strong universality, excellent multiplying power performance and long cycle stability. The graphene carbon-based current collector improves the flexibility of the device when the electrode has high conductivity. The flexible electrode coated with SGE electrolyte can realize dynamic re-infiltration and self- repairing of the electrode material under the condition of not damaging the package layer through the gel-sol transition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of the dynamic self-repairing water system chargeable flexible zinc ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the fabrication process of a flexible Zinc-ion battery based on sol-gel electrolyte in the dynamic self-repairing aqueous rechargeable flexible zinc ion battery (Drawing includes non-English language text).
