Abstract
Carbon nanostructures are used to prepare electrode compositions for lithium ion batteries. In one example, an anode for a Li ion battery includes three-dimensional carbon nanostructures made of highly entangled nanotubes, fragments of carbon nanostructures and/or fractured nanotubes, which are derived from the carbon nanostructures, are branched and share walls with one another. Amounts of carbon nanostructures employed can be less than or equal to 0.5 weight % relative to the weight of the electrode composition.
