More Information
Summary:Disclosed is a powder comprising a lithium-containing compound and a nickel-containing mixed metal compound, and satisfying the following requirements of (1) and (2) when the powder is analyzed by plasma emission spectrometry of particles: (1) an absolute deviation of a synchronous distribution chart against an approximated straight-line is 0.10 or less, wherein the approximated straight-line is evaluated from a synchronous distribution chart obtained by plotting an emission intensity of lithium and an emission intensity of nickel of each particle composing of the powder, and (2) a release rate of lithium evaluated by the following formula is 80 or less: Release rate of lithium=(nb/na)×100 wherein, na is the number of particles containing lithium in the powder, and nb is the number of particles containing lithium and not containing nickel in the powder.
