Abstract
An electrochemically active material including composite particles that each include a graphene-based material shell surrounding nanoparticles of a core material. The composite particles may include a BET surface area of less than about 75 m/g. The electrochemically active material may be formed into an electrode incorporated within a lithium ion electrochemical cell.
