1. An electrochemical cell, comprising:
a) a casing; and
b) a wound-shaped electrode assembly housed inside the casing, the wound-shaped electrode assembly comprising:
i) an anode comprising:
A) an anode current collector having opposed anode current collector major sides; and
B) an anode having a proximal U-shaped anode connecting portion connected to an anode inner portion extending to an anode inner portion distal end, and connected to an anode outer portion extending to an anode outer portion distal end, wherein the anode current collector has an anode active material contacted to its opposed major sides extending from the anode inner portion distal end, through the proximal U-shaped anode connecting portion, and to the anode outer portion distal end;
ii) a cathode comprising:
A) a cathode current collector having opposed cathode current collector first and second major sides; and
B) a cathode material contacted to the opposed first and second major sides of the cathode current collector so that the cathode has opposed cathode first and second major sides extending from a cathode proximal end to a cathode distal end;
iii) a separator disposed intermediate the U-shaped anode and the cathode to prevent direct physical contact between them; and
iv) a catholyte in electrochemical association with the U-shaped anode and the cathode,
v) wherein, in the wound-shaped electrode assembly, the proximal U-shaped anode connecting portion directly faces the cathode proximal end, the anode inner portion directly faces the cathode first major side, and the anode outer portion directly faces the cathode second major side with the anode inner and outer portions residing side-by-side from adjacent to the proximal end of the anode outer portion to the anode inner portion distal end and with the anode inner and outer portions facing the opposed cathode first and second major sides in a first 360° rotation about a center point of the wound-shaped electrode assembly and continuing in a second rotation about the center point with a distal segment of the anode outer portion extending outwardly for a greater distance beyond the distal ends of both the anode inner portion and the cathode so that the distal segment of the anode outer portion is in a direct facing relationship with the anode outer portion residing in the first 360° rotation without there being any segment of the anode inner portion and the cathode between the direct facing relationship of the distal segment of the anode outer portion in the second rotation and the anode outer portion in the first 360° rotation.
