Lithium vapor lithiated anode Materials for lithium ion batteries and lithium ion batteries comprising the same

摘要

The present invention relates to a negative electrode active material material for a lithium secondary battery, specifically, a negative electrode active material material made in an alloy state by adding lithium metal in advance to silicon particles, graphite, silicon oxide, or other negative electrode active materials, and a method of manufacturing the same, and from It relates to a manufactured lithium-ion battery. In addition, the moment the negative electrode active material, which has been additionally treated with lithium metal inside and outside the negative electrode material, is taken out into the air through heat treatment in a vacuum atmosphere, it reacts with moisture and oxygen in the air, so that no flame is generated.
