Negative electrode active material and negative electrode including the same
Composite particles and a negative electrode active material including such particles for an electrochemical device. The negative electrode active material is capable of lithium intercalation/deintercalation and includes composite particles including a carbon phase including a carbonaceous material, silicon (Si) and lithium fluoride (LiF). The Si and LiF may be present as Si—LiF mixed particles, which are dispersed in the carbon phase, wherein the Si—LiF mixed particles are dispersed in the carbon phase with uniform or non-uniform distribution. In addition, the composite particles include the carbon phase mixed uniformly or amorphously with the Si—LiF mixed particles.
