  • Catalyst containing solid electrolytes
    Patent number: 5580680
    Abstract: A solid electrolyte that includes (1) a first catalyst that is capable of initiating the polymerization of solvent components at elevated temperatures in order to increase the resistance (or impedance) of the solid electrolyte and thereby prevent thermal runaway and/or (2) a second catalyst that is capable of initiating the polymerization of flammable substances (e.g., olefins) in the solvent and batteries make therefrom are provided. To assure that the catalysts do not prematurely initiate polymerization below a certain temperature, the catalysts may be microencapsulated within a heat sensitive material that disintegrates or dissolve at a predetermined elevated temperature to release the catalysts. Microencapsulation permits the controlled release of the catalysts into the electrolyte under the appropriate conditions.

  • Solid electrolytes containing tetrabutyl ammonium thiocyanate and electrochemical cells produced therefrom
    Patent number: 5532082
    Abstract: Solid electrolytes containing a source of lithium cations and a source of thiocyanate anions and methods for preparing electrolytic cells from such solid electrolytes are provided. Preferably the solid electrolyte includes LiPF.sub.6 and [CH.sub.3 (CH.sub.2).sub.3 ].sub.4 NSCN. The tetrabutyl ammonium cation also acts as a surfactant which improves the coatability of the electrolyte mixture prior to being cured. The thiocyanate anion improves the lithium plating process by adsorbing onto and modifying the lithium anode surface.
