INSOLUBLE ANODE HAVING POROUS FILM LAYER CONTAINING ELECTRODE ACTIVE MATERIAL NANOSPHERE AND A METHOD OF MANUFACTURING THE INSOLUBLE ANODE

摘要

The present invention relates to an insoluble anode having a porous film layer containing electrode active material nano-spheres. Specifically, the insoluble anode having a porous film layer containing electrode active material nano-spheres comprises: an anode substrate made of metal which can be anodized; a porous film layer containing sintered powder of the metal and electrode active material nano-spheres; and an electrode active material coating layer formed on the inner and outer surface of the porous film layer. The porous film layer comprises 60-90% of the volume of the sintered powder of the metal and 10-90% of the volume of the electrode active material nano-spheres. In addition, the present invention relates to a manufacturing method of the insoluble anode.
