MANUFACTURING METHOD OF ELECTRODE OF POWER STORAGE DEVICE, ELECTRODE OF POWER STORAGE DEVICE, AND POWER STORAGE DEVICE

摘要

PURPOSE: A manufacturing method of electrode of power storage device is provided to uniformly disperse active material, to maximize the performance of the active material, and to obtain a coated electrode in which impurity is hardly remained. CONSTITUTION: A manufacturing method of electrode of power storage device comprises: a step of manufacturing slurry by dispersing an active material of which particle diameter is 100nm or less, a conductive aid, a binder, and an organic acid of which molecular weight is 193 or less into non-aqueous solvent; a step of spreading the slurry on a current collector; and a step of heating the slurry for evaporating the non-aqueous solvent. The current collector is metal foil. The active material is a material selected from the group consisting of lithium iron phosphate, carbon, and activated charcoal.
