Lithium metal composite oxide, positive electrode active material for lithium secondary battery, positive electrode and lithium secondary battery |
abstract |
Provided are a lithium metal composite oxide having low battery internal resistance and excellent output characteristics, a positive electrode active material for a lithium secondary battery using the lithium metal composite oxide, a positive electrode, and a lithium secondary battery. A lithium metal composite oxide that can be doped / undoped with lithium ions and includes at least nickel and satisfies all of the following requirements (1) to (3). (1) The BET specific surface area is 1.0 m 2 / g or less. (2) The ratio (X / Y) is 1.1 or more and 2.9 or less when the average secondary particle diameter D 50 is X μm and the calculated particle diameter is Y μm. However, the calculated particle size is calculated by the following method. Calculated particle size (Y) = 2 × 3 / (BET specific surface area × tap density) (3) Ratio of residual lithium amount (mass%) contained in lithium metal composite oxide to BET specific surface area (m 2 / g) Is 0.25 or less.
