Abstract
The present invention provides positive and negative electrodes, for a lithium secondary battery, allowing a battery to be quickly and fully charged in a very short period of time, for example, within one minute and allowing the battery to be used for vehicles at low temperatures. An organic electrolytic solution is permeated into an electrode group formed by winding positive and negative electrodes or by laminating the positive and negative electrodes one upon another with a separator being interposed therebetween to repeatingly occlude and release lithium ions. The positive electrode active substance and the negative electrode active substance have at least one phase selected from among a graphene phase and an amorphous phase as a surface layer thereof. An activated carbon layer is formed on a surface of the positive electrode active substance and that of the negative electrode active substance.
