Abstract
A battery and ultracapacitor device for use in a vehicle includes a positive electrode, a first negative electrode, a second negative electrode, a first separator disposed between the positive electrode and the first and second negative electrodes, and a controller communicating with the positive electrode, the first negative electrode, and the second negative electrode. A first negative electrode has a first composition and communicates with the first positive electrode. The second negative electrode has a second composition and is adjacent to the first negative electrode and a second separator. The second negative electrode communicates with the positive electrode and the first negative electrode. The first negative electrode comprises a secondary battery negative electrode. The second negative electrode comprises an ultracapacitor negative electrode.
