摘要

It provides a positive electrode active material capable of achieving both a low alkali content and a high external volumetric energy density even in a composition having a high Li ratio. The metal composition is Li _a Ni _b Co _c Mn _1-bc (Wherein, 1.40≤a≤1.48, 0.16≤b≤0.17, 0.16≤c≤0.17.) Oxide-based positive electrode active material for a lithium ion battery having a residual alkali content of 0.7 mass% or less.
