"thin film, flexible, polymer capacitors store and discharge high density of electrical energy while tolerating heat and electric fields... capacitors made from the new polysulfates, when enhanced with a thin film of aluminum oxide, could discharge a high density of energy, while withstanding electric fields (more than 700 million volts per meter) and temperatures (150 degrees C) that would destroy most in current use... could see wide application, including in electric vehicle power systems"
