Lithium-containing transition metal oxide target, process for producing the same and lithium ion thin film secondary battery |
摘要 |
Proposed are a lithium-containing transition metal oxide target formed from a sintered compact of lithium-containing transition metal oxides showing a hexagonal crystalline system in which the sintered compact has a relative density of 90% or higher and an average grain size of 1 μm or greater and 50 μm or less, and a lithium-containing transition metal oxide target formed from a sintered compact of lithium-containing transition metal oxides showing a hexagonal crystalline system in which the intensity ratio of the (003) face, (101) face and (104) face based on X-ray diffraction using CuKα ray satisfies the following conditions: (1) Peak intensity ratio of the (101) face in relation to the (003) face is 0.4 or higher and 1.1 or lower; and (2) Peak ratio of the (101) face in relation to the (104) face is 1.0 or higher. In addition to this lithium-containing transition metal oxide target optimal for forming a thin film positive electrode for use in a thin film battery such as a three-dimensional battery and a solid state battery, also proposed are its production method and a lithium ion thin film secondary battery. In particular, the present invention aims to propose a positive electrode target capable of obtaining a thin film with superior homogeneity. |
