  • Bis (perfluoralkanesulfonyl)imide surfactant salts in electrochemical systems
    Patent number: 6280883
    Abstract: Electrolyte compositions and electrochemical systems containing such compositions are described where the electrolyte includes in a matrix material a combination of a conductive salt and a bis(perfluoroalkanesulfonyl)imide surfactant salt. The compositions improve wettability of electrodes and separators while maintaining and improving conductivity, stability, and compatibility with other cell components.

  • Batteries with porous components
    Patent number: 6171723
    Abstract: Approaches are described for producing porous, polymer electrodes with good characteristics for incorporation into polymer batteries. Two preferred processes are presented. The polymer electrodes can be subjected to additional processing to increase their porosity and electrical conductivity. The polymer electrodes preferably are incorporated into a polymer battery where the components are laminated together.
