METHOD FOR MANUFACTURING ANODE ACTIVE MATERIALS FOR LITHIUM SECONDARY ELECTRIC CELL

摘要

PURPOSE: An active material of an anode of a secondary lithium electric cell is provided to improve charge and discharge properties, thermal stability and capacity, and to reduce manufacturing cost of the active material. CONSTITUTION: A method for manufacturing active material of an anode of a secondary lithium electric cell is comprised of the steps of: mixing lithium-nickel group oxide with lithium-manganese group oxide, in which less than 1% of lithium-manganese group oxide by weight of the lithium-nickel group oxide is added; adding a binding agent to the mixture; and applying a low-temperature treatment to the resultant. Preferably, the temperature for the heat treatment in the manufacturing procedure is 200-500 deg.C.
