What is a Lithium-ion capacitor？
Capacitors are power storage devices that are classified as secondary batteries.Various types of capacitors have been developed depending on the materials used, but there are generally two types of capacitors with large capacities: "Electric Double Layer Capacitors (EDLC)" and "Lithium-ion Capacitors".

Features
The feature of capacitors is that electricity goes in and out (charges/discharges) very quickly.Compared to well-known power storage devices (lithium-ion secondary batteries, lead-acid batteries, etc.), the energy density is inferior, but the power density is excellent, the performance deterioration due to repeated charging and discharging is small, and the life is long.
