ELECTROCHEMICAL CELL WITH ANODE MATERIAL IN PROTRUSION

An electrochemical cell comprises a can comprising a cylindrical side wall extending from a closed end wall, the closed end wall defining a protrusion with a protrusion cavity therein; and a separator positioned within the can and defining an inner cavity and separating the inner cavity from an outer cavity defined by the can and the separator. The inner cavity extends into the protrusion cavity. The electrochemical cell further comprises a cathode electrode material disposed in the outer cavity; and a anode electrode material disposed in at least a portion of the inner cavity.
