摘要

Provided is a positive electrode active material capable of achieving a low alkali amount and a high appearance volume energy density even with a high Li ratio. A metal composition of an oxide-based positive electrode active material for a lithium ion battery is represented by Li_aNi_bCo_cMn_1-b-c (in the formula, 1.40 = a = 1.48, 0.16 = b = 0.17, 0.16 = c = 0.17), and the amount of residual alkali contained is 0.7% by mass or less.
