A cathode active material for a lithium secondary battery and a manufacturing method therefor and a lithium secondary battery using said active material and a setup module of said lithium secondary battery using said cathode active material

摘要

The purpose of the present invention is to provide a cathode active material for a lithium secondary battery to give said battery a long-lasting high output property, and to disclose a method of manufacturing said active material and a lithium secondary battery using said active material, and to provide a setup module composed of a combination of plurality of said batteries. The present invention is characterized by a cathode active material for a lithium secondary battery and a method of manufacturing said active material, a lithium secondary battery using said active material, and a setup module of batteries composed of a combination of a plurality of said lithium secondary batteries, wherein said cathode active material is an electrostatically and/or mechanically gathered aggregation of oxide which, having the form of a primary particle, includes lithium and manganese, said aggregation separates into discrete primary particles by an external physical force.
