Electrode assembly for high energy devices

A battery, comprising:

• a) an anode strip;
• b) a cathode strip disposed substantially parallel to the anode strip, the anode strip and the cathode strip being folded together such that the electrode assembly has multiple alternating layers of anode strip and cathode strip and such that a first side of the electrode assembly curves substantially along a single arc and a second side opposite the first side curves substantially along a plurality of arcs;
• c) a layer of an insulating separator material disposed between the anode strip and the cathode strip;
• and
• d) an electrolyte activating and operatively associating the anode strip and the cathode strip.

A method of providing an electrode assembly, comprising the steps of:

• a) providing an anode strip having a first end, a second end opposite the first end, and a body disposed therebetween;
• b) folding one of the ends of the anode strip over a portion of the body of the anode strip to form an anode loop;
• c) providing a cathode strip having a first end, a second end opposite the first end, and a body disposed therebetween;
• d) folding one of the ends of the cathode strip over a portion of the body of the cathode strip to form a cathode loop;
• e) placing the anode strip and the cathode strip together with a separator therebetween to form a combined anode and cathode electrodes such that one of the ends of the anode strip terminates inside the cathode loop in the cathode strip and such that one of the ends of the cathode strip terminates inside the anode loop in the anode strip;
• f) folding the combined anode and cathode electrodes to form a folded, combined anode and cathode electrodes;
• and
• g) folding the folded, combined anode and cathode electrodes to form an electrode assembly having a first side that curves substantially along a single arc and having a second side opposite the first side that curves substantially along a plurality of arcs.
