NOVELTY - Flexible zinc ion hybrid capacitor includes a positive electrode, a negative electrode and an electrolyte, where the positive electrode adopts a flexible, self-supporting and electrochemically active activated carbon fiber. The activated carbon fiber is prepared by a secondary activation process. USE - Flexible zinc ion mixed capacitor for use in electrochemical energy storage application (Claimed). ADVANTAGE - The capacitor has high electrochemical activity, flexible and self-supporting performance and better flexibility and deformable capability and electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a flexible zinc ion hybrid capacitor, which involves: (A) preparing zinc salt into a 0.1-3 mol/L aqueous solution, and then adding to the aqueous solution containing monomers, crosslinkers and initiators under stirring conditions for crosslinking for 10-30 minutes, or adding to the aqueous solution containing the gel in a swollen state under stirring conditions to form an uncured electrolyte glue; and (B) assembling the flexible zinc ion hybrid capacitor in the order of the negative electrode, the uncured gel electrolyte glue containing zinc salt, and the positive electrode, and after the gel electrolyte is fully polymerized, obtaining the flexible zinc ion hybrid capacitor.
