Surface treated silica containing particles are combined with a resin to form a liquid prepolymer composition for use in additive manufacturing. A surface treatment on the silica containing particles may participate in polymerization of the composition. The silica containing particles may be colloidal silica or a silica polymer composite particle.

Composition for liquid-based additive manufacturing

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.

Anode electrode compositions for battery applications

Carbon nanostructures are used to prepare electrode compositions for lithium ion batteries. In one example, carbon nanostructures, fragments of carbon nanostructures and/or fractured carbon nanotubes are provided in an aqueous dispersion that can be used in the manufacture of silicon-containing anodes. The aqueous dispersion can further include another conductive carbon additive such as carbon black.
