Compared to conventional secondary batteries, DLCAPs (Double Layer Capacitors) can withstand high current charge and discharge cycles, offering excellent cycle life as energy storage devices. In recent years, there has been increasing focus on energy issues such as reduced oil consumption, decreased power consumption, CO2 reduction, and effective utilization of new energy sources. Research and development on incorporating EDLCs (Electric Double Layer Capacitors) for new applications are actively underway.

In addition, discussions and research on deploying EDLCs in hybrid vehicles and fuel cell vehicles to enhance energy efficiency are accelerating. Japan's Kyocera Group is actively promoting the commercialization of environmentally friendly products aimed at energy savings and low environmental impact, with EDLCs serving as representative products.

EDLCs are available in a wide range of specifications from several hundred Farads to 2300 Farads, providing a broad capacity range to meet customer needs. They find applications in areas such as automotive, energy storage, and electric hand tools, among others.
