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&#x2014;LiF mixed particles, which are dispersed in the carbon phase, wherein the Si&#x2014;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&#x2014;LiF mixed particles.
