▎ 摘　　要

NOVELTY - Preparing flexible super capacitor involves using phytic acid/graphene oxide modified foam carbon by mixing phytic acid and graphene solution uniformly in presence of foam carbon to obtain precursor solution, placing prepared precursor solution in hydrothermal reaction kettle, obtaining black sheet-shaped solid after sealing, reacting and cooling at room temperature, drying prepared black sheet-shaped solid, and pressing on current collector at 10-20 megapascal to obtain flexible super capacitor electrode. USE - Method for preparing flexible super capacitor. ADVANTAGE - The method enables to have better mechanical performance, electrochemical performance and simple and safe operation, requires cheap and easily available raw material, and in eco-friendly manner.
