ABSTRACT:
An organic electrolyte capacitor is provided with a high energy density, a high power and a high capacitance even at −20°. The organic electrolyte capacitor has a high discharge capacity even at a temperature as low as −20° C., while having a high voltage and a high energy density. The structure of the organic electrolyte capacitor includes a positive electrode, a negative electrode, and an electrolyte capable of transporting lithium ions. The positive electrode can reversibly support lithium ions and anions, and the negative electrode can reversibly support the lithium ions by using a mesopored carbon material having a pore volume of 0.10 ml/g or more for a pore diameter of 3 nm or larger.
