1. A nanographitic composite for use as an anode in a lithium ion battery, comprising:

  • particles of an electroactive material; and

    a coating layer comprising a plurality of graphene nanoplatelets having a thickness of 0.34 nm to 50 nm and a lateral dimension of less than 900 nm, whereinthe electroactive particles have a lateral dimension that is larger than the lateral dimension of the graphene nanoplatelets, andthe graphene nanoplatelets coat at least a portion of the nanoscale particles to form a layer made up of overlapping graphene nanoplatelets.
