A three-dimensional electrode architecture for a supercapacitor and/or battery characterized by high power density and high energy density, the three-dimensional electrode architecture comprising:
- at least one negative electrode;
- at least one positive electrode;
- said at least one negative electrode and said at least one positive electrode each having a thickness, a width and a height, and said at least one negative electrode and said at least one positive electrode are disposed in an interpenetrating manner.
A three-dimensional supercapacitor or battery characterized by high power density and high energy density, the three-dimensional supercapacitor or battery comprising:
- at least one negative electrode;
- at least one positive electrode;
- wherein said at least one negative electrode and said at least one positive electrode each have a thickness, a width and a height, and said at least one negative electrode and said at least one positive electrode are disposed in an interpenetrating manner;
- an electrolyte in contact with the electrodes;
- and
- an outer insulating case.
A method for making a three-dimensional supercapacitor or battery, said method comprising:
- a first extrusion deposition of a first layer of a positive electrode, a negative electrode and an insulating outer case, wherein the first layer positive and negative electrodes are disposed in an interpenetrating manner and the first layer insulating outer case is disposed around said first layer interpenetrating positive and negative electrodes;
- a second extrusion deposition of a second layer of a positive electrode, a negative electrode and an insulating outer case, wherein the second layer positive and negative electrodes are disposed in an interpenetrating manner and the second layer insulating outer case is disposed around said second layer interpenetrating positive and negative electrodes, and wherein the first layer and the second layer are in register one with the other;
- a deposition of an electrolyte between the positive and negative electrodes;
- and
- a final encapsulation of the three-dimensional supercapacitor or battery.
