    摘要： A cathode includes a lithium transition metal complex compound including lithium, one, or two or more transition metals, magnesium, and oxygen as constituent elements. In a standardized X-ray absorption spectrum of the lithium transition metal complex compound measured by an X-ray absorption spectroscopic method, a first absorption edge having absorption edge energy E1 in X-ray absorption intensity of about 0.5 exits in a range where X-ray energy is from about 1303 eV to about 1313 eV both inclusive, in a discharged state in which a discharge voltage is about 3.0 V, and a second absorption edge having absorption edge energy E2 in X-ray absorption intensity of about 0.5 exits, in a charged state in which a charge voltage V is from about 4.3 V to about 4.5 V both inclusive. The absorption edge energies E1 and E2 and the charge voltage V satisfy a relation of E2−E1≧(V−4.25)×4.

    摘要： An object is to provide a power storage device with high discharge capacity and high energy density. The power storage device includes a positive electrode in which a positive electrode active material is formed over a positive electrode current collector; and a negative electrode which faces the positive electrode with an electrolyte interposed therebetween. The positive electrode active material includes a film-form first region which includes a compound containing lithium and nickel; and a film-form second region which includes a compound containing lithium and one or more of iron, manganese, and cobalt, but not containing nickel. The first region is covered with the second region. Since a superficial portion of the positive electrode active material does not contain nickel, nickel is not in contact with an electrolyte solution; thus, generation of a catalyst effect of nickel can be suppressed, and a high discharge potential of nickel can be utilized.

    摘要： A process of manufacturing a positive active material for a lithium secondary battery includes adding a metal source to a doping element-containing coating liquid to surface-treat the metal source, wherein the metal source is selected from the group consisting of cobalt, manganese, nickel, and combination thereof; drying the surface-treated metal source material to prepare a positive active material precursor; mixing the positive active material precursor with a lithium source; and subjecting the mixture to heat-treatment. Alternatively, the above drying step during preparation of the positive active material precursor is substituted by preheat-treatment or drying followed by preheat-treatment.
