<p>A supercapacitor based on electrochemical active materials in liquid phase, in which the major energy storage method is based on the reaction of electrochemical active materials in the thin liquid layer near inner and outer surfaces of the porous electrode. 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. The positive electrode liquid contains at least one kind of electrochemistry active materials of positive and negative electrode liquid. The electrochemistry oxidation and reduction reaction mainly takes place on the inner surfaces of the positive and negative electrodes. This supercapacitor has a high power density, large pseudo capacity, high single charging and discharging energy density, an excellent cycle property and a long life.</p> |
