摘要： An energy storage device before pre-doping includes positive electrodes, negative electrodes, separators, a cover, an electrolyte solution, a positive terminal, a negative terminal, and pre-doping metal foil. Each of the positive electrodes and the negative electrodes respectively include: positive collector foil and negative collector foil each having holes; and a positive active-material layer and a negative active-material layer arranged on at least one side of the collector foil. Either one or both of the positive electrodes and the negative electrodes include a pre-doping-targeted electrode, in which the pre-doping metal foil is arranged in direct contact with the surface of the active-material layer, and a non-arrangement part, in which the pre-doping metal foil is not arranged, is formed in at least part of the outer periphery of the active-material layer.

摘要： Provided is a lithium ion capacitor that can retain a capacity under a high temperature environment and has small increase in internal resistance while using an aqueous binder for a positive electrode. A lithium ion capacitor includes: a positive electrode; a negative electrode; and an electrolytic solution contacting the positive electrode and the negative electrode. The electrolytic solution includes an organic solvent and a lithium salt electrolyte having an imide structure; the positive electrode includes a collector foil and a positive electrode active material; and the positive electrode active material is held onto the collector foil through a binder including a polymer having a RED value to the electrolytic solution of more than 1, the RED value representing a relative energy difference with respect to the electrolytic solution based on Hansen solubility parameters.
