Long-Term Wide-Temperature Supercapacitor Ragone Plot Based on Manufacturer Datasheet

Methodology for obtaining realistic supercapacitor (SC) Ragone from manufacturer datasheet only is presented in this letter, allowing to predict long-term wide-temperature SC power and energy performance for given terminal voltage limits. Analytical derivations are based on the simplified RC equivalent SC model, connected to a constant power element, taking into account manufacturer provided age a...
