Patent ID: 8871379

Claim:
An electrochemical cell, which comprises: a) a casing; b) an anode comprising: i) a body of lithium as an anode active material, the body comprising spaced apart front and back major lithium body faces extending to a sidewall defining an anode thickness; and ii) a metal strip comprising an anode current collector, wherein the metal strip comprises spaced apart front and back major strip faces extending to and meeting with a metal strip edge, and wherein the metal, strip extends from at least one proximal metal strip portion to a distal metal strip portion having a distal metal strip end; iii) wherein the spaced apart front and back major strip faces of the at least one proximal metal strip portion extend within respective front and back planes in the anode thickness between the front and back major lithium body faces, and iv) wherein lithium directly contacts the front and back major strip faces and the metal strip edge of the at least one proximal metal strip portion, and v) wherein the proximal metal strip portion contacted by lithium is devoid of perforations, and vi) wherein the distal metal strip portion is electrically connected to an anode terminal; and c) a cathode of at least one cathode active material contacted to at least one side of a cathode current collector; d) a separator disposed between the anode and the cathode to prevent direct physical contact between them; and e) a nonaqueous electrolyte activating the anode and the cathode housed inside the casing.
