PRODUCTION OF POSITIVE ELECTRODE MATERIAL FOR LITHIUM ION SECONDARY CELL

摘要

PROBLEM TO BE SOLVED: To provide this production of the positive electrode material consisting of a lithium-containing multiple metal oxide which is subjected to sufficient crystal growth and capable of exhibiting high performance. SOLUTION: In this production that comprises firing a precursor material of a lithium-containing multiple metal oxide to produce the positive electrode material consisting of the lithium-containing multiple metal oxide, the precursor material is fired while supplying an oxygen-containing gas, with a rotary kiln provided with a rotary block which has at least three blades and at least two of these three blades of which are placed so as to be in contact with the inner wall of the rotary kiln.
