摘要： Disclosed are a negative electrode active material and a lithium rechargeable battery. The negative electrode active material may include a graphite core being configured to absorb and release lithium. The graphite core may include pores extending from an outer surface of the graphite core to the inside of the graphite core. The pores may include metal nano-particles and amorphous carbon. The lithium rechargeable battery may include a positive electrode plate including a positive electrode active material configured to absorb and release lithium ions, a negative electrode plate including the negative electrode active material configured to absorb and release lithium ions, a separator interposed between the positive electrode and negative electrode plates and electrolyte configured to transport the lithium ions.
