A SUPERCAPACITOR BASED ON ELECTROCHEMISTRY ACTIVE MATERIALS IN LIQUID PHASE

摘要

A supercapacitor based on electrochemistry active materials in liquid phase, in which the major energy storage manner is based on the reaction of the electrochemistry active materials in the thin liquid layer near inner and outer surfaces of the porous electrodes. The supercapacitor at least comprises one unit, the unit has positive and negative electrode collectors (11,15), positive and negative electrode chambers ( 12, 14), as well as a separator. Positive and negative electrode chambers ( 12, 14) are porous electrodes, positive and negative electrode liquid is immersed in the pores in a nonflowing state, positive electrode liquid containsat least one kind of electrochemistry active materials of positive electrode, negative electrode liquid contains at least one kind of electrochemistry active materials of negative electrode. The electrochemistry oxidation and reduction reaction is taken place at the inner surfaces of the positive and egative electrodes. The supercapacitor has high power density, large pseudo-capacity, high single charging and discharging energy density, excellent cycle property and long ife.
