An electrochemical cell comprising a casing, an anode comprising anode active material, a cathode, and an electrolyte solution activating the cathode and the anode is described. In one embodiment, the cathode is comprised of a first current collector, first and second sheets of a first cathode active material in contact with the first current collector, a second current collector, third and fourth sheets of the first cathode active material in contact with the second current collector, and a first sheet of a second cathode active material in non-adherent and congruent contact with the second and third sheets of the first cathode active material. |
