POSITIVE POLAR METERIALS AND ITS MAUFACTURING METHOD OF SECONDARY BATTERY

摘要

The present invention relates to a positive electrode material comprising: a positive electrode active material mixture including a positive electrode active material produced from an active material precursor and a lithium compound, a conductive material and a binder; and an active material precursor as an additive, wherein the active material precursor as the additive is the same as the active material precursor as a material of the positive electrode active material.
