▎ 摘　　要

NOVELTY - Holey graphene comprises graphene with multiple of holes, and a catalyst point adsorbed on the surface of the graphene. USE - The holey graphene is useful in energy storage device i.e. fuel cell and lithium secondary battery and act as catalyst for anode of battery (all claimed). ADVANTAGE - The holey graphene has excellent material transfer capability by forming holes in graphene as simple heat treatment to increase surface area, and has advantage of able to mass-synthesize. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) producing holey graphene, comprising (a) forming multiple holes in graphene through heat treatment to prepare holey graphene, (b) dispersing the catalyst point in a solvent to prepare a catalyst point dispersion, (c) preparing a mixture by supplying the holey graphene to the catalyst point dispersion, (d) filtering the prepared mixture, and (e) obtaining and drying powder from the upper layer of the filtered mixture; and (2) energy storage device comprising holey graphene.
