The invention discloses a high-performance manganese dioxide electrode and a preparation method thereof. Compared with manganese dioxide prepared by a traditional electrochemical method, the specific volume characteristic of the manganese dioxide electrode material prepared by ultrasonic oscillation treatment and an ammonium cation-assisted electrochemical deposition technology is doubled. The energy storage characteristics of lithium manganese batteries and super capacitors assembled by using the manganese dioxide electrode are far superior to those of the existing reports. The electro-deposition technology can be realized in one step, namely, a plurality of deposition steps are not needed, the process is simple, the operation is convenient, the controllability and the repeatability are high, and the yield is high. The technology provided by the invention is a good choice for preparing a new generation of manganese dioxide electrode material. |
