Claim 18:
19. An electrochemical cell, comprising:
a) a casing; and
b) an electrode assembly housed inside the casing, the electrode assembly comprising:
i) a U-shaped lithium anode comprising lithium contacted to opposed major sides of an anode current collector, the U-shaped 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 residing in the anode inner portion, in the proximal U-shaped anode connecting portion and in the anode outer portion has 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 comprised of acetylene black contacted to a 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, wherein the catholyte comprises either thionyl chloride or sulfuryl chloride containing a mixture of LiAlCl4 and LiGaCl4 dissolved therein,
v) wherein the cathode resides inside the U-shaped anode so that the anode inner portion directly faces the cathode first side, and the anode outer portion directly faces the cathode second side with the proximal U-shaped anode connecting portion facing the cathode proximal end, and
vi) wherein, with the anode, the cathode and the separator as a wound-shaped electrode assembly encircling a center point of the electrode assembly, an imaginary anode reference radius extending outwardly from the center point intersects the anode proximal connecting portion at a tangent point, and wherein the anode inner and outer portions do not contact each other until the anode inner portion has crossed the imaginary anode reference radius after the imaginary anode reference radius intersects the anode connecting portion at the tangent point.
