COMPOSITE ANODE, AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME

The present disclosure relates to a composite anode and a secondary battery including the same, the composite anode including a silicon-containing structure; a first carbon material; a second carbon material; and a conductive material, wherein the first carbon material has a specific surface area (BET) value of 1.5 m/g or less, a rate of change of the specific surface area (m/g) to an increase in particle size (μm) is −0.07 to −0.04 m/μm·g, and an area occupied by pores in a cross-section of the first carbon material is 10% or less.
