Negative electrode active material for lithium secondary battery, method of preparing the same, and lithium secondary battery including the material
Provided are a negative electrode active material for a lithium secondary battery and a method of preparing the same, wherein since the negative electrode active material includes porous polycrystalline silicon and the porous polycrystalline silicon includes pores disposed at grain boundaries, the negative electrode active material may exhibit a buffering action by internally absorbing changes in volume of the active material during charge and discharge. As a result, lifetime characteristics of a negative electrode and a battery may be improved.
