    Abstract: The Si-block copolymer core-shell nanoparticles include: a Si core; and a block copolymer shell including a block having relatively relatively high affinity for Si and a block having relatively low affinity for Si and forming a spherical micelle structure around the Si core. Since the Si-block copolymer core-shell nanoparticles exhibit excellent dispersibility and stability in a mixed solution including the same, the Si-block copolymer core-shell nanoparticles are easily applied to an anode active material for lithium secondary battery by carbonization thereof. In addition, since the anode active material for lithium secondary battery using the Si-block copolymer core-shell nanoparticles includes carbonized Si-block copolymer core-shell nanoparticles and pores, the anode active material has long lifespan, high capacity and high energy density, and the block copolymer shell of the carbonized Si-block copolymer core-shell nanoparticles can improve lifespan of lithium secondary battery by buffering volumetric change thereof during charge and discharge.
