Testing Electrochemical Capacitors Part 2: Cyclic Charge-Discharge and Stacks

This application note is Part of 2 describing electrochemical techniques for energy-storage devices. It explains Gamry’s PWR800 measurement software and describes techniques to investigate electrochemical capacitors. This application note can also be extended to testing batteries. An introduction to electrochemical capacitors is found in Part 1 of this application note, which discusses techniques familiar to chemists who have worked outside of energy-storage applications. Part 3 describes theory and practice of EIS measurements on capacitors.
