PURPOSE: To provide high capacity and high voltage by using metal oxide for a positive electrode, using insoluble and infusible substrate having a polyacene group skeletal structure for a negative electrode, properly controlling quantity of lithium in a battery, and selecting a carrying method for lithium derived from the negative electrode. CONSTITUTION: Metal oxide containing lithium is used for a positive electrode 1, while a substance composed of insoluble and infusible substrate (PAS) is used for a negative electrode 2. In other words, PAS used for the negative electrode 2 is prepared by heating aromatic group condensation polymer and is provided with an atomic ratio of hydrogen atoms to carbon atoms of 0.5-0.05 and a polyacene group skeletal structure. To the negative electrode 2PAS, total quantity of lithium contained in a battery is 500mAh/g or more, while quantity of lithium derived from the negative electrode 2 is 100mAh/g or more, and lithium derived from the negative electrode 2 is electrochemically carried by using cyclic carbonate solvent solution of lithium salt. Then, both of quantity of lithium in the battery and quantity of lithium derived from the electrode 2 are properly controlled, and consequently, the battery provided with high capacity and high voltage can be obtained. |
