Abstract:In this paper, permanganate as electrode materials for electrochemical capacitors, the burning time of different systems, the electrochemical properties of manganese oxide as the working end, a variety of modern methods of physical tests and electrochemical methods of material preparation, characteristics and capacitance its impact factor, capacitor formation mechanism. Constant current charge-discharge, cyclic voltammeter experiments show the assembly of the manganese oxide capacitor has a good electrochemical performance. 

　　　The use of liquid combustion products prepared with the appropriate reagents, and measured the electrochemical properties, with acetic acid and nitric acid as raw materials, the first synthesis using ()2 + (3)2 = 1:1 mixed with 10ml (about 20% of the total volume) of water into the preparation of manganese solution, and then prepared to take a good amount of liquid solution of manganese in a crucible, in accordance with the requirements of different conditions, place the crucible in the muffle furnace heating (constant temperature of 400℃) recorded in the heating process changes, the time was 10min, 30min, 1h, 3h and 6h, the roasting is complete, remove the resulting products (,,etc.) characterization of electrochemical properties of the product, in the end battery test system, test its electrical properties, and analysis of electrical properties.
