Method for sintering lithium contained electrode material
A method for sintering lithium contained electrode material includes: depositing a mixture of a particle like lithium compound and a substance M in a metal container, where M is a chemical element selected from a group consisting of iron (Fe), phosphor (P), cobalt (Co), nickel (Ni), manganese (Mn), vanadium (V), and carbon (C), or an oxide or compound thereof; subjecting the mixture deposited in the metal container to heat treatment by heating the metal container in two phases of which temperature ranges for heating are respectively 300-700° C. and 500-900° C.; and grinding the heat-treated mixture to obtain a powder like lithium contained electrode material. According to the method of the present invention, in the process of sintering and synthesis, it is not necessary to supply an external (or a great amount of) protective gas, so that substantial reduction of processing cost and time is realized.
