The method of producing granulated powder for a lithium ion secondary battery positive electrode active material

Volume capacity density, packing density and high safety, and a lithium ion secondary battery positive electrode active material having excellent charge and discharge cycle durability, to provide a method useful granulated powder as a raw material. Ni source, Co sources and Mn sources, or Ni source, from aqueous solution of Co source and Al source, coprecipitated the coprecipitate particles, desalted and spray dried granules having a substantially spherical method for producing a granulated powder, characterized in that to obtain.
