New Polymer Capacitors Store 4x More Energy at High Heat

What Happened The Penn State research team, led by electrical engineering researcher Qiming Zhang, created a capacitor using a novel polymer blend that maintains high energy storage capacity even under extreme heat. Published in the prestigious journal Nature, their study demonstrates that these new capacitors can function at temperatures reaching 250°C while storing roughly four times the energy density of today’s advanced polymer capacitors. This represents a significant advancement over current technology, where polymer capacitors typically max out around 100°C operating temperature.
