| description | An electrochemical device includes a positive electrode having a positive electrode material layer containing a conductive polymer doped with a first anion and a second anion, a negative electrode having a negative electrode material layer storing and releasing lithium ions, and a nonaqueous electrolytic solution having lithium ionic conductivity. The second anion is more easily dedoped from the conductive polymer than the first anion. At an end period of charge of the electrochemical device, a number of moles M1 of the first anion and a number of moles M2 of the second anion respectively doped in the conductive polymer satisfy a relationship of M1 < M2. At an end period of discharge of the electrochemical device, a number of moles M3 of the first anion and a number of moles M4 of the second anion respectively doped in the conductive polymer satisfy a relationship of M3 > M4. |
