Abstract
The present invention provides for high performance lithium-ion capacitor laminate cells that include positive electrodes, negative electrodes and organic solvent electrolyte with lithium salt, and a method for making said high performance lithium-ion capacitor laminate cells. These high performance lithium-ion capacitor laminate cells of the present invention, include a negative electrode which is pre-doped with sufficient lithium ions by employing lithium sources including lithium powder known as SLMP or thin lithium films on the surface of negative electrodes, and this pre-doping with placing lithium sources on negative electrode surface results in LIC laminate cells with considerably higher performance in specific energy, specific power and cycle life.
