BIPOLAR SUPERCAPACITORS AND METHODS FOR MAKING SAME
First Claim
1. A bipolar element for energy storage comprising:
- two end electrodes with a dedicated means for connecting to a potential source;
at least one intervening electrode disposed between the end electrodes or after each of the end electrodes, wherein the intervening electrode has no connection to a potential source;
a separator disposed after each of the electrodes for concentrically winding the electrodes and the separators into a round element;
one end of the round element being sealed with the adhesive;
the other end of the round element being injected with an electrolyte to saturate the electrodes and the separators; and
a housing for containing the sealed and soaked round element to form an energy-storage device that contains two identical bipolar groups wherein all electrodes are connected in series, and the two bipolar groups are connected in parallel by sharing the two end electrodes.

Abstract
The present invention relates to a bipolar element for energy storage, which facilitates the manufacturing thereof with high working voltage. The bipolar element for energy storage includes two end electrodes with a dedicated means for connecting to a potential source; at least one intervening electrode disposed between the said end electrodes wherein the said intervening electrode has no connection to a potential source; and a separator disposed after each electrode for concentrically winding the said electrodes and separators into a jelly roll; or a separator disposed between every two electrode for stacking the said electrode and separator into a prismatic form; an organic electrolyte solution is added to the said separators for storing energy with a potential applied to the said end electrodes by the said power supply, wherein the bipolar element is partially sealed. The said assemblies of making high voltage supercapacitors in single units or modules can facilitate the usage of the devices as power managers in high power applications for automobiles, power tools, machineries and automatic system.
