  • POROUS COMPOSITE ELECTRODE HAVING RATIO GRADIENT OF ACTIVE MATERIAL/CURRENT-COLLECTING MATERIAL BY THREE-DIMENSIONAL NANOSTRUCTURE, METHOD FOR MANUFACTURING ELECTRODE AND SECONDARY BATTERY INCLUDING THE ELECTRODE
    Publication number: 20220052347
    Abstract: A three-dimensional porous composite electrode includes a three-dimensional porous current-collector and an active material layer including an active material and having a three-dimensional structure along a surface of the three-dimensional porous current-collector. The three-dimensional porous current-collector extends along a first direction, includes a current-collecting material and has a porosity gradient along a second direction perpendicular to the first direction. The three-dimensional porous composite electrode has a ratio gradient of the active material to the current-collecting material along the second direction.
