Active material for Anode, Method for manufacturing the same, And Secondary Battery and Super Capacitor including the Same

摘要

PURPOSE: A negative electrode active material is provided to ensure the high capacity property of silicon and the stability of lithium titanate by comprising silicon particles and lithium titanate aggregates. CONSTITUTION: A negative electrode active material comprises: lithium titanate aggregates(100) in which a plurality of lithium titanate particles(110) are aggregated; and a plurality of silicon particles(200) that surrounds the lithium titanate aggregate. The negative electrode active material comprises a plurality of first carbon nanotubes(120) arranged within the lithium titanate aggregate and a plurality of second carbon nanotube(210) surrounding the lithium titanate aggregate. The diameter of the lithium titanate particles is 80-150 nm.
