1. An electrode composition, comprising:
an active anode material; and
at least one material selected from the group consisting of: carbon nanostructures, fragments of carbon nanostructures and fractured multiwall carbon nanotubes,
wherein the active anode material includes graphite, silicon, SiOx, silicon-graphite composite or lithium titanate
wherein the carbon nanostructures or fragments of carbon nanostructures include a plurality of multiwall carbon nanotubes that are crosslinked in a polymeric structure by being branched, interdigitated, entangled and/or sharing common walls, and
wherein the fractured multiwall carbon nanotubes are derived from carbon nanostructures and are branched and share common walls with one another.
