Supercapacitor electrode for high temperature manufactureing method of the electrode and Supercapacitor for high temperature using the electrode

摘要

The present invention relates to an electrode active material, 0.1 to 20 parts by weight of a conductive material with respect to 100 parts by weight of the electrode active material, and 1 to 20 parts by weight of a binder with respect to 100 parts by weight of the electrode active material, To 5 atomic%, a method for producing the electrode, and a high-temperature super capacitor using the electrode for the high-temperature super-capacitor. According to the present invention, it is possible to prevent deterioration of electrochemical performance by minimizing the oxygen functional groups present in the electrode active material, to reduce gas generation of the electrolyte when used as an electrode active material of a high-temperature supercapacitor, The cost can be high and the decomposition voltage can be increased.
