Bridging Batteries and Supercapacitors

Yury Gogotsi, PhD, Distinguished University and Bach professor in Drexel’s College of Engineering

For decades researchers and technologists have regarded batteries and capacitors as two distinct energy storage devices — batteries, known for storing more energy but releasing it slowly; capacitors, for quickly discharging it in smaller spurts. Each new energy storage device has therefore been categorized as
