▎ 摘　　要

NOVELTY - A high-fold graphene material preparing method involves pickling magnetite/graphene composite material, and drying to obtain final product. USE - Method for preparing a high-fold graphene material. ADVANTAGE - The method enables preparing a high-graded graphene material with high pleat graphene material, better effects of increasing specific surface area and increasing channel ion transfer to realize super capacitor energy storage performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a high-graded graphene material.
