Abstract
Provided is a hybrid capacitor with an excellent long-term stability. A hybrid capacitor includes a positive electrodeincluding a positive-electrode active material layercontaining a carbon material employing a porous structure or a fibrous structure with an electric double layer capacity, and a negative electrodeincluding a negative-electrode active materialcontaining a material capable of adsorbing and releasing lithium ions. A lithium compound that traps protons is disposed between the positive-electrode active material layerand the negative-electrode active material layer. This hybrid capacitor further includes a separatordisposed between the positive-electrode active material layerand the negative-electrode active material layer, and the separator contains the lithium compound.
