STEP2-1 Special characteristics and stability of Lithium Ion Capacitors High reliability at high temperatures and high stability Those are the conspicuous characteristics of Lithium Ion Capacitors

Lithium Ion Capacitors are hybrid capacitors that combine the properties of an electrical double-layer capacitor, with a lithium rechargeable battery. The positive electrode has the physical adsorption (surface) properties of an electric double-layer capacitor, while the negative electrode has the oxidation reduction reaction of a lithium rechargeable battery.
By doing this the merits of both systems: the long life of an electrical double-layer capacitor, and the high capacity of a Lithium Ion rechargeable battery; are realized in one capacitor.
