Disclosed is an electrochemical cell, comprising: a substantially cylindrical, conductive container having a closed end, an open end sealed by an end assembly, and a sidewall extending between the closed end and the open end; a positive electrode comprising iron disulfide; a negative electrode having a length an a width consisting essentially of lithium or a lithium alloy having at least 90 wt. % lithium and having a cumulative surface area; a separator; a nonaqueous, organic electrolyte; an internal lead located in the container and in electrical contact with the negative electrode, wherein the lead has a surface area that is connected to less than 0.7% of the cumulative surface area of the negative electrode, and wherein the positive electrode, the negative electrode and the separator are wound into a jellyroll electrode assembly so that the internal lead makes electrical contact with the container or the end assembly, and wherein a theoretical, interfacial anode-to-cathode input capacity ratio for the cell is less than 1.0. |
