Abstract
A hybrid power device having three electrodes and a method for fabricating the same are provided. The hybrid power device includes a lithium secondary battery and a supercapacitor in a cell and has three electrodes. The three electrodes have a common electrode including a positive electrode of the lithium secondary battery, which is as the positive electrode of the supercapacitor, a negative electrode of the lithium secondary battery including lithium metal and the other electrode of the supercapacitor. This hybrid power device is superior to that of a lithium secondary battery, and further is more economical and practical than a case where a lithium secondary battery and a supercapacitor are individually fabricated and used as a hybrid.
