Abstract

A hybrid lithium ion capacitor battery and method of making the same is disclosed. The hybrid lithium ion capacitor battery includes a positive electrode separated from a negative electrode by a separator layer. A first activated carbon layer is disposed between the separator layer and one of the positive and negative electrodes. The first activated carbon layer is coated on a first surface of the separator layer. A second activated carbon layer is disposed between the separator layer and the other of the positive and negative electrodes. The second activated carbon layer is coated on a second surface of the separator layer. A first current collector coextensively contacts the first electrode and a second current collector coextensively contacts the second electrode. An electrolytic solution carries lithium cations between the positive and negative electrodes through the activated carbon coated separator layer.
