Abstract:
1. A method for sintering lithium contained electrode material, comprising: depositing a mixture of a particle like lithium compound and a substance M in a cover-closed metal container with a tightness of engagement therebetween, 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 cover-closed metal container to heat treatment by heating the cover-closed metal container in a first heating phase with a first temperature of 300-700° C. and a second heating phase with a second temperature of 500-900° C. respectively, so as to form an internal protection and an external protection to prevent the mixture from being oxidized; and grinding the heat-treated mixture to obtain a powder like lithium contained electrode material.
