Kind Code:
B2
Abstract:
To provide an oxide-based positive electrode active material for an all-solid lithium ion battery, which has a high capacity and a high tap density.SOLUTION: A precursor of an oxide-based positive electrode active material for an all-solid lithium ion battery is represented by the compositional formula, (NixCoyMn1-x-y)CO3 (where 0.16≤x≤0.17 and 0.16≤y≤0.17). The precursor has an average particle diameter D50 of 7.0-17.0 μm, a tap density of 1.6-2.0 g/cc, a circularity of 0.88-0.95, and a porosity of 2-10% in a particle cross section.SELECTED DRAWING: None
