摘要： Provided are an anode active material for a lithium secondary battery, a method for preparing same, and a lithium secondary battery including same. An anode active material for a lithium secondary battery according to the present invention includes: active particles by means of which lithium ions may be absorbed/released; and a coating layer coated on the surface of the active particles, wherein the coating layer includes a first material which is a hollow nanofiber and a second material which is a carbon precursor or LTO. When silicon is used as an anode active material for a lithium secondary battery, cracks are generated and active material particles are destroyed due to a change in volume, through the reaction with lithium ions during charging/discharging. However, the anode active material for a lithium secondary battery of the present invention may prevent the capacity from being radically reduced as the charge/discharge cycle proceeds, thereby extending cycle life, and thus achieving a high energy density appropriate for a high-capacity battery.

Thus, when the exterior case expands by an increase in the pressure therein, the exterior case is brought into contact with the punching pin, and a through-hole is formed in the exterior case. The secondary battery of the present invention is configured such that the through-hole is formed in the exterior case when the exterior case expands by the increase in the pressure therein, and the gas in the exterior case is discharged to the outside to prevent explosion thereof. In addition, the protruding length of the punching pin can be adjusted to easily control through-hole forming time, and sharp fractures are prevented from being formed at the secondary battery to protect users from injury.
