Abstract
The present invention provides a nickel atom-, manganese atom- and cobalt atom-containing composite carbonate that is high in specific surface area and large in tap density, and useful as a raw material for producing a lithium nickel manganese cobalt composite oxide to be used in a positive electrode active material for use in a lithium secondary battery, and provides a method for industrially advantageously producing the composite carbonate. The composite carbonate includes nickel atoms, manganese atoms and cobalt atoms, and has an average particle size of 5 μm or more and less than 20 μm, a BET specific surface area of 40 to 80 m2/g and a tap density of 1.7 g/ml or more.
