This shows that the super-capacitor plays a role in protecting the battery and prolonging the service life of the battery. The hybrid energy storage device can increase the life cycle of the combined system, reduce the emission of waste batteries, and protect the environment.
The integrating systems comprising of batteries and supercapacitors termed as hybrid devices with one shadowing the limitation of the other. Battery electrode contributes to the energy storage advantage while the supercapacitor electrode contributes to the power density advantage.
Super-capacitor can greatly increase the output power of the battery. In Experiment 1, it has been determined that the existence of super-capacitor can alleviate the irregular voltage/current impact on the battery and improves the discharge efficiency of the battery. Experiment 2 is to explore the charging sequence and its influence on the battery.
To meet the demands of all kinds of multifunctional electronics which need energy storage systems with high energy and power densities, the hybridization of batteries and supercapacitors is one of the most promising ways.
