3 Supercapacitors

Double-layer and pseudocapacitive storage, how to tell them apart, and how to report capacitance, energy and power.

Lessons

Double layers, pseudocapacitance and battery-type materials, and the b-value test. About 25 minutes

CV and galvanostatic charge and discharge, two- versus three-electrode cells, energy, power and cycling. About 30 minutes

Capacitance from CV and charge–discharge curves, energy and power, and the b-value analysis.
