Title: ELECTROCHEMICAL DEVICE
Abstract:
An electrochemical device in which are combined a positive electrode that includes an electroconductive polymer in which anions can be doped or dedoped, and a negative electrode that includes a negative-electrode material that can store or discharge lithium ions, wherein float characteristics are maintained. The electrochemical device is provided with: a positive electrode that includes, as a positive-electrode active material, an electroconductive polymer in which anions can be doped or dedoped; a negative electrode that includes a negative-electrode active material in which lithium ions can be stored and discharged; and an electrolyte containing anions and lithium ions. The total amount A (mol) of monomer units constituting the electroconductive polymer included in the positive electrode, and the total amount B (mol) of anions included in the electrochemical device, satisfy the relationship 0 < B/A < 0.7.
