Title:
SINTERED BODY COMPRISING LiCoO2, SPUTTERING TARGET, AND PRODUCTION METHOD FOR SINTERED BODY COMPRISING LiCoO2
Document Type and Number:
WIPO Patent Application WO/2014/142197
Kind Code:
A1
Abstract:
Provided is a sintered body that comprises LiCoO2 and that is used in a sputtering target. The area (A) of a surface of the sintered body that corresponds to a sputtering surface is 200-1500 cm2 and the relative density of the entire sintered body is 75% or more. When (B1) represents the area of a region in which the area ratio that is occupied by pores is 10% or higher in the surface that corresponds to a sputtering surface, the ratio of (B1) to the area (A) is 50% or higher, and the area (B2) of a region having a resistivity of 1.0 × 102 Ω·cm or less in the surface that corresponds to a sputtering surface occupies 25% or more of the area (A).
