Electrochemical Capacitor Performance Compared with the Performance of Advanced Lithium Batteries

摘要

Electrochemical capacitors have orders-of-magnitude faster response times than the most powerful high-rate lithium-ion batteries; Batteries are clearly the most optimum solution in applications with long-duration regenerative capture times; Capacitors are clearly the most optimum solution in applications with short-duration regenerative capture times; The transition time is ～20 s for the components examined; Thermal management requirements in some cyclic applications may make capacitors the optimum solution for regen times out to ～200 s; Today's best system will probably remain the best system tomorrow.
