    摘要： A high power lithium-ion secondary battery having an increased capacity and capable of maintaining high discharge voltage and repeating charging/discharging high current. A lithium-ion secondary battery having; an electrode group formed by laminating or winding a negative electrode layer and a positive electrode layer so as to interpose a separator made of synthetic resin, the negative electrode layer containing a material capable of intercalating/deintercalating lithium-ion, and a positive electrode layer including a lithium-containing metallic oxide; and a non-aqueous electrolyte containing lithium salt, where the electrode group is immersed. The positive electrode material unit contains a fluorinated lithium-containing metallic oxide as a main material, and the separator possesses a hydrophilic group. Further, the positive electrode material preferably contains a main material including LiNi x Co y Mn z O 2 , where 0.4 ≤ x ≤ 1,0≤ y ≤ 0.2, 0 ≤ z 0.2, x + y + z = 1.

    摘要： 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. An activated carbon layer having a specific surface area not less than 1000m 2 /g is formed on a surface of the positive electrode active substance and that of the negative electrode active substance.
