  • Electrochemical cell constructions and methods of making the same
    Patent number: 6737189
    Abstract: A method of making electrochemical cells with high anode-to-cathode interfacial surface area and improved discharge efficiency at high rate discharge, without sacrificing total capacity involves the use of a separator coated electrode, and a flowable material comprising a second electrode. The first electrode and flowable material comprising the second electrode are disposed in a cell housing. The flowable material surrounds the coated surfaces of the first electrode. The invention also provides simplified methods for making electrochemical cells having a high anode-to-cathode interfacial surface area.
