Zusammenfassung:LICORICE ROOT RESIDUE-BASED HIERARCHICAL POROUS CARBON, PREPARATION METHOD AND APPLICATION THEREOF The present invention relates to the technical field of carbon material, and in particular to a licorice root residue-based hierarchical porous carbon, and a preparation method and application thereof. The preparation method provided by the present invention has simple steps and is suitable for industrial production; recycling of resource is achieved with licorice root residue as a precursor; meanwhile, the licorice root residue-based hierarchical porous carbon prepared by the preparation method features high specific surface area and rational pore size distribution, resulting in high energy density when serving as an electrode material.
