AGGREGATED GRANULAR LITHIUM MULTIPLE OXIDE, ITS PRODUCTION AND LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To produce a lithium multiple oxide having high fluidity and to obtain a lithium ion secondary battery using the lithium multiple oxide as an active material of a positive electrode and having a high initial discharge capacity and high discharge capacity retentivity. SOLUTION: Many particles of a fine powder of the formula LixNi1-y-zCoyMezO2 (where Me is a metal element or a transition metal element whose atomic number is >=11 with the exception of Ni and Co, 0
