ELECTROCHEMICAL DEVICE ELECTRODE, METHOD FOR MANUFACTURING SAME, AND ELECTROCHEMICAL DEVICE

摘要

The present invention relates to a supercapacitive electrochemical device electrode formed by using chemical impregnation, a method for manufacturing same, and an electrochemical device. The electrochemical device electrode of the present invention comprises a current collector; and an active material layer on the current collector, wherein the active material layer contains a metal hydroxide nano-wire of which one longitudinal end is in an upward direction. Accordingly, a supercapacitor of the present invention has high capacitance, high output, and high energy density.
