Patent ID: 8241788

Claim:
A method for providing an electrochemical cell, comprising the steps of: a) providing an anode; b) providing a cathode comprising the steps of: i) pressing a first cathode active material having a relatively high energy density but a relatively low rate capability at a first pressure to form a first cathode active material blank; ii) positioning the first cathode active blank in a pressing fixture contacting a first major side of a first cathode current collector and a second cathode active blank of a material having a relatively low energy density but a relatively high rate capability contacting a second, opposite major side of the first cathode current collector to form a cathode assembly; and iii) pressing the cathode assembly at a second pressure that is less than the first pressure; c) providing a separator intermediate the anode and cathode in electrical association with each other; and d) activating the anode and cathode with a electrolyte.
