Small Energy Store Capacitors

Balancing energy storage with charge and discharge times. While they can’t store as much energy as a comparably sized lithium-ion battery (they store roughly ¼ the energy by weight), supercapacitors can compensate for that with the speed of charge. ... Wide-ranging Operating Temperatures. Supercapacitors have a much broader effective operating temperature (from roughly -40F to +150F). What are the advantages of supercapacitor modules vs batteries? Supercapacitors offer higher power densities, longer lifetimes and cycle lifes, require virtually no maintenance, inherently safe operation and have wide operating temperatures. All of these features combine for lower total cost of ownership in applications requiring high power and/or short runtimes.
