▎ 摘　　要

NOVELTY - The additive consists of flaky shaped graphene-based particles having size distribution of about 0.01-5 microns in planar direction, 0.1-50 nanometers in thickness direction. The particles are provided with through holes having diameters of about 1-1000 nanometers with specific porosity. USE - Porous conductive additive. ADVANTAGE - The porous additive having very high conductivity efficiency can optimize pore structure in electrode and reduce ion conducting paths. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of porous conductive additive. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the porous conductive additive.
