Title:
ACTIVE MATERIAL, ELECTRODE, AND POWER STORAGE ELEMENT
Document Type and Number:
Japanese Patent JP2020187881
Kind Code:
A
Abstract:
To provide an active material that forms a high-density power storage element electrode that has high energy density and high output characteristics.SOLUTION: An active material includes a porous carbon with a plurality of pores forming a three-dimensional network structure, and a conductive polymer, and at least some of the plurality of pores in the porous carbon includes the conductive polymer, and has two or more peaks in a particle size distribution curve showing a relationship between the volume particle size and the volume frequency by the laser diffraction scattering type particle size distribution measurement method for the porous carbon.SELECTED DRAWING: Figure 2
