Systems and methods for electrical energy storage

An electrical energy storage apparatus, comprising:

• an interpenetrating, three dimensional, triply periodic structure including:
• an electrolyte material;
• a first non-planar layer of anode material to form an anode;
• a second non-planar layer of cathode material which conforms to a contour of the first non-planar layer of anode material, and which forms a cathode;
• the first non-planar layer and the second non-planar layer being formed so as to be interpenetrating in a triply periodic configuration, and which form a plurality of wall portions, and where the wall portions form non-parallel channels throughout the interpenetrating, three dimensional, triply periodic structure;
• a first current collector layer in communication with the first non-planar layer and forming a first electrode;
• a second current collector layer in communication with the second non-planar layer and forming a second electrode;
• and
• a third non-planar layer forming a separator material disposed between the first non-planar layer and the second non-planar layer, and following the contour of the first non-planar layer and the second non-planar layer, with the first non-planar layer, the second non-planar layer and the third non-planar layer forming integrated wall portions propagating in the interpenetrating, three dimensional, triply periodic structure;
• wherein the integrated wall portions forming the interpenetrating, three dimensional, triply periodic structure repeat periodically and uniformly in a plurality of differing non-parallel directions to provide channels extending in uniform, repeating patterns in the plurality of differing non-parallel directions, and wherein the integrated wall portions form uniform thicknesses;
• and
• wherein each of the first and second non-planar layers of material forming the anode and cathode, respectively, are exposed on opposing sides of the integrated wall portions throughout an interior of the structure.
