Claim 15:
16. A method for preparing an anode composition, the method comprising:
forming an aqueous dispersion that includes a dispersant, carbon nanostructures, fragments of carbon nanostructures and/or fractured multiwall carbon nanotubes, wherein the content of carbon nanostructures, fragments of carbon nanostructures and/or fractured multiwall carbon nanotubes in the aqueous dispersion is from about 0.2 to about 1.5 wt %, and the aqueous dispersion is stable against sedimentation for at least 4 weeks; and
combining the aqueous dispersion with an anode active material to form the anode composition,
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,
wherein the multiwall fractured carbon nanotubes are derived from carbon nanostructures and are branched and share common walls with one another.
