An alkali metal electrochemical cell having the cathode comprising at least two distinct active mixtures having differing formulations of a discharge promoter component mixed with electrode active material, is described. The active mixture contacting the current collector has a greater percentage of the discharge promoter component than the remainder of the cathode, and a preferred electrode active material is fluorinated carbon.
