In contrast to secondary batteries, super-capacitors, also known as “electrochemical double-layer capacitors” (EDLC), offer higher power density and life cycle but have considerably lower energy density. Super-capacitors currently find use as short-term power buffers or secondary energy storage devices in renewable energy, power systems [12, 13].
