摘要： Provided is a spinel-type lithium-manganese-containing complex oxide that is related to a 5 V-class spinel, and with which output characteristics and charge-discharge cycle ability can be enhanced while suppressing gas generation. Proposed is a spinel-type lithium-manganese-containing complex oxide comprising at least Li, Mn, O, and two or more other elements, and having an operating potential of 4.5 V or more with respect to a metal Li reference potential, wherein: D50 is 0.5 to 9 μm; a value of (|mode diameter−D50|/mode diameter)×100 is 0 to 25%; a value of (|mode diameter−D10|/mode diameter)×100 is 20 to 58%; a ratio of average primary particle diameter/D50, which is calculated from an average primary particle diameter calculated from a SEM image and the D50, is 0.20 to 0.99; and a primary particle is a polycrystal.

摘要： A positive electrode active material comprising a lithium metal composite oxide having a layered crystal structure provides a novel lithium metal composite oxide powder which can suppress the reaction with an electrolytic solution and raise the charge-discharge cycle ability of a battery, and can improve the output characteristics of a battery. A lithium metal composite oxide powder comprises a particle having a surface portion where one or a combination of two or more (“surface element A”) of the group consisting of Al, Ti and Zr is present, on the surface of a particle comprising a lithium metal composite oxide having a layered crystal structure, wherein the amount of surface LiOH is smaller than 0.10% by weight, and the amount of surface Li2CO3 is smaller than 0.25% by weight; in an X-ray diffraction pattern, the ratio of an integral intensity of the (003) plane of the lithium metal composite oxide to that of the (104) plane thereof is higher than 1.15; and the amount of S obtained by a measurement using ICP is smaller than 0.10% by weight of the lithium metal composite oxide powder (100% by weight).

摘要： Provided is a new 5 V class spinel-type lithium manganese-containing composite oxide which enables the expansion of a high potential capacity region and the suppression of gas generation. The 5 V class spinel-type lithium manganese-containing composite oxide has an operating potential of 4.5 V or more at a metal Li reference potential, and contains Li, Mn, O and two or more other elements. The spinel-type lithium manganese-containing composite oxide is characterized in that, in an electronic diffraction image from a transmission electron microscope (TEM), a diffraction spot observed in the Fd-3m structure as well as a diffraction spot not observed in the Fd-3m structure are confirmed.
