  • Method and apparatus for preparing electrochemical cells
    Patent number: 5746781
    Abstract: A method of fabricating electrochemical cells and batteries wherein the successive anode and cathode layers are separated by a polymeric electrolyte layer having a protruding polymer edge around its perimeter which reduces the likelihood of inadvertent contact between the anode and cathode current collectors is provided. The polymer edge functions as a non-conducting physical barrier positioned between adjacent current collectors. An apparatus for preparing electrochemical cells is also disclosed.
    Type: Grant

  • Method of preparing electrodes
    Patent number: 5616152
    Abstract: A method of fabricating electrodes suitable for use in electrochemical cells is provided. Each electrode has a perforated current collector and a tab which form an integral unit. The method can be adapted for batch, semi-continuous, or continuous fabrication of electrodes having electrode material laminated onto one or both surfaces of the current collector.
