Process for producing lithium-containing composite oxide for positive electrode for lithium secondary battery
摘要：
It is to provide a positive electrode active material for a lithium secondary battery, which has a large volume capacity density and high safety, is excellent in uniform coating properties and is excellent in the charge and discharge cyclic durability and low temperature characteristics even at a high charge voltage. A process for producing a lithium-containing composite oxide represented by the formula LipQqNxMyOzFa (wherein Q is at least one element selected from the group consisting of titanium, zirconium, niobium and tantalum, N is at least one element selected from the group consisting of Co, Mn and Ni, M is at least one element selected from the group consisting of Al, alkaline earth metal elements and transition metal elements other than the Q element and the N element, 0.9≦p≦1.1, 0
