Method For Preparing Lithium manganese oxide And Lithium manganese metal oxide With Spinel And Nanostructure

摘要

The present invention relates to a method for producing a lithium manganese oxide having a spinel crystal structure, and nanostructures, manganese comprising heat treatment by preparing an oxide, the manganese solid-phase reaction method, and a step wherein the mixture to form a mixture by mixing a lithium salt to the oxide (Solid-state reaction), the formula of said lithium manganese oxide is LiMn ₂ O _{4 is} ; In addition, the present invention relates to a method for producing a lithium manganese oxide having a spinel crystal structure and nano-structure, preparing a manganese oxide, the method comprising heat treatment by mixing a lithium salt and a metal salt to the manganese oxide by forming a mixture, and the mixture was solid-phase reaction method (Solid-state reaction), the lithium manganese metal oxide of formula LiM _x Mn _(2-x) O ₄ (0 & x & 2, M is a metal). The ; method for producing a lithium manganese oxide and lithium manganese oxide having a spinel crystal structure and the nano-structure of the present invention, because the use of manganese is less environmentally friendly and attractive manufacturing costs. In addition, the lithium manganese oxide made by the method and a lithium manganese metal oxide may be used as a cathode active material for lithium secondary battery.
