▎ 摘  要

NOVELTY - The crumpled particle synthesizing method involves forming a graphene dispersion solution with micron-sized graphene-based material sheets then nebulizing the graphene dispersion solution to form aerosol droplets. The aerosol droplets are passed through a horizontal tube furnace pre-heated at a predetermined temperature by a carrier gas then dries to concentrate and compress the micron-sized graphene-based material sheets into crumpled particles of sub-micron scale. USE - Synthesizing method of crumpled particle (claimed) e.g. crumpled paper ball used as electrode material of article (claimed) e.g. microbial fuel cell. Uses include but are not limited to battery, capacitor, catalysis, polymer composite. ADVANTAGE - Provides high electron conductivity and high accessible surface area in solution, while allowing rapid mass transfer of the fuels and ions due to open structure. Facilitates microbial diffusion and colonization since crumpled particles are packed into a solid with rough surface. Crumpled graphene particles delivers superior performances of electricity generation to objects covered with activated carbon and regular sheet-like graphene, leading to significantly higher short-circuit current and maximum power density.
