Abstract
A lithium ion capacitor having high energy density, high output density, high capacity and high safety includes a positive electrode made of a material capable of being reversibly doped with lithium ions and/or anions, a negative electrode made of a material capable of being reversively doped with lithium ions, and an aprotic organic solution of a lithium salt as an electrolytic solution. Wherein, the positive electrode and the negative electrode are laminated or wound with a separator interposed between them, the area of the positive electrode is smaller than the area of the negative electrode. The face of the positive electrode is substantially covered by the face of the negative electrode when they are laminated or wound.
