New compound that withstands extreme heat and electricity could lead to next-generation energy storage devices

Society’s growing demand for high-voltage electrical technologies—including pulsed power systems, cars and electrified aircraft, and renewable energy applications—requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical conditions. Researchers at Lawrence Berkeley National Laboratory and Scripps Research have now developed a new polymer-based device that efficiently handles record amounts of energy while withstanding extreme temperatures and electric fields.
