The concept of Lithium Ion Capacitor

An ULTIMO lithium ion capacitor cell is composed of a pre-doped Carbon anode, similar to a lithium ion battery negative electrode. The positive electrode consists out of Activated Carbon, like electric double layer capacitor cathodes.

By using our unique know-how of pre-doping negative electrodes with lithium ions, it is possible to offer next-generation electricity storage devices that achieve a combination between high power density and high energy density, are safe in use and exhibit superior life characteristics.
