ANODE ACTIVE MATERIAL FOR SECONDARY BATTERY, ANODE, SECONDARY BATTERY USING ANODE, AND METHOD FOR MANUFACTURING SECONDARY BATTERY

摘要

The present invention relates to: an anode active material for a secondary battery capable of having a long lifespan and a large battery capacity and being large and cheap by using, as a main component, graphite having excellent stability and a long lifespan and using, as an additive, a senary Si alloy having large battery capacity; an anode; a secondary battery using the anode; and a method for manufacturing the secondary battery. The anode for a secondary battery of the present invention is characterized by comprising an anode current collector and an anode active material formed on at least one surface of the anode current collector; the anode active material is characterized by containing 70-90 wt% of graphite and 10-30 wt% of a senary Si alloy; and the senary Si alloy is characterized by being composed of amorphous nanofibers.
