This whitepaper draws an analogy between supercapacitors and batteries using the analogy of athletes in a sprint versus a marathon. It explains how supercapacitors, like sprinters, excel at delivering large bursts of energy quickly for short durations, while batteries, like marathon runners, provide consistent energy over longer periods but struggle with rapid increases in transient power. The paper explores the management of energy and applications of both technologies in various scenarios, highlighting their strengths and limitations.
