Abstract
An electrochemical device includes a positive electrode, a negative electrode, and a separator disposed between these electrodes. The positive electrode includes a positive current collector containing a first metal, a carbon layer containing a conductive carbon material, a barrier layer disposed between the positive current collector and the carbon layer, and an active layer disposed on the carbon layer. The barrier layer has conductivity and higher acid resistance than the positive current collector. The active layer contains a conductive polymer. The first metal is preferably aluminum.
