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.
