Three-dimensional electrode structure and battery having the electrode structure

A battery comprising:

• a first electrode structure;
• an electrolyte layer provided on the first electrode structure;
• and
• a second electrode structure on the electrolyte layer such that the electrolyte layer is interposed between the first and second electrode structures;
• wherein the first electrode structure comprises:
• an electrode collector plate;
• a plurality of first active material plates disposed on the electrode collector plate and protruding from the electrode collector plate;
• and
• a plurality of partition walls disposed on the electrode collector plate and perpendicular to the plurality of active material plates in a plan view,
• wherein the plurality of first active material plates has a planar shape,
• wherein the partition wall is perpendicular to the electrode collector plate,
• wherein the electrolyte layer is interposed between the electrode collector plate and an upper surface of the partition wall facing the electrode collector plate such that the electrolyte layer includes:
• a first surface facing the electrode collector plate;
• and
• a second surface opposite to the first surface and facing the upper surface of the partition wall, and
• wherein the first surface of the electrolyte layer and the second surface of the electrolyte layer are disposed on the upper surface of the partition wall.
