CONDUCTIVE POLYMER PARTICLE AND PRODUCTION METHOD THEREFOR, AND POSITIVE ELECTRODE FOR POWER STORAGE DEVICE USING THE SAME AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide conductive polymer particles excellent in capacity density and a production method therefor, and to provide a positive electrode for power storage device using the same and a manufacturing method therefor.SOLUTION: Conductive polymer particles, where the particle surface is modified by protonic acid treatment, are used as a formation material of a positive electrode for power storage device.
