Type selection and technology of graphitization kiln for preparation of anthracite based anode materials
Anthracite has a porous and short-range microcrystalline and microdomain structure,which is an ideal material for the prepa-ration of lithium anode materials.By heating anthracite to 2 800～3 000℃in Acheson furnace,the carbon anode material for lithium battery with excellent performance can be obtained.The graphitization process of anthracite is the key point for the preparation of an-thracite based negative electrode materials.For the 40 tons/year pilot project of anthracite based negative electrode materials,the fur-nace type size of the graphitization kiln is determined,and the current,voltage and power curve and other parameters during the heating process of the graphitization furnace are calculated and determined.
