- - SILICON-CARBON COMPOSITE NEGATIVE ELECTRODE MATERIAL NEGATIVE ELECTRODE COMPRISING THE SILICON-CARBON COMPOSITE NEGATIVE ELECTRODE MATERIAL AND SECONDARY BATTERY COMPRISING THE NEGATIVE ELECTRODE

摘要

The present invention is a core comprising SiO X (0≤X<2); a carbon layer covering at least a portion of the surface of the core; a carbon nanotube structure positioned on the carbon layer; and polyvinylidene fluoride covering at least a portion of the carbon nanotube structure, wherein the carbon nanotube structure is a structure formed by arranging and bonding 2 to 5,000 single-walled carbon nanotube units side by side with each other, and the A portion of the carbon nanotube structure relates to a silicon-carbon composite anode active material bonded to the carbon layer, an anode including the same, and a secondary battery.
