MANUFACTURING METHOD OF SECONDARY PARTICLES AND MANUFACTURING METHOD OF ELECTRODE OF POWER STORAGE DEVICE

摘要

The conductivity of an active material layer provided in an electrode of a secondary battery is sufficiently increased and active material powders in a slurry containing active materials each have a certain size. Secondary particles are manufactured through the following steps: mixing at least active material powders and oxidized conductive material powders to form a slurry; drying the slurry to form a dried substance; grinding the dried substance to form a powder mixture; and reducing the powder mixture. Further, an electrode of a power storage device is manufactured through the following steps: forming a slurry containing at least the secondary particles; applying the slurry to a current collector; and drying the slurry over the current collector.
