Abstract

A three-dimensional electrode structure design system according to an embodiment of the present invention may comprise: a structure forming module configured to form a conductive additive and binder (CBD) structure using a first design parameter input for the CBD structure, and form an electrode structure using a second design parameter input for the electrode structure; a calculation module configured to calculate an effective electrical conductivity of the CBD structure using an intrinsic electrical conductivity of a conductive additive and an intrinsic electrical conductivity of a binder, calculate an effective electrical conductivity of the electrode structure using an intrinsic electrical conductivity of the active material, an intrinsic electrical conductivity of CBD particles, and an intrinsic electrical conductivity of the current collector, and calculate a calculated resistivity of the electrode structure by converting the effective electrical conductivity of the electrode structure into a reciprocal; a correction module configured to calculate a deviation by comparing the calculated resistivity with a target resistivity and correct a variable or shape of an electrode structure in a direction of minimizing the deviation; and a backtracking module configured to calculate the intrinsic electrical conductivity of the active material, the intrinsic electrical conductivity of CBD particles, the intrinsic electrical conductivity of the current collector, and a third design parameter, all of which are included in the corrected electrode structure.
