Patent ID: 8053113

Claim:
A nanocomposite binder for an electrode mix of a secondary battery, the binder comprising: carbon nanotubes; and one or more organic components selected from a photo- and/or thermo-polymerizable material selected from epoxy-, urethane-, acrylate-, silicon-, hydroxyl-based monomers and acrylic derivatives, a low molecular weight polymer of the photo- and/or thermo-polymerizable material selected from polyvinyl alcohol, polyester acrylate, epoxy acrylate, urethane acrylate and polyurethane, a mixture of the photo- and/or thermo-polymerizable material and the low molecular weight polymer, and a polymer selected from polyvinyl alcohol, polyimide, polyacrylic acid, and styrene butadiene rubber, wherein individual carbon nanotubes of the carbon nanotubes are interposed between the polymers of the photo- and/or thermo-polymerizable material, wherein the individual carbon nanotubes are chemically bonded to the one or more organic components, and wherein the carbon nanotubes are contained in an amount of 0.01 to 20% by weight, based on the total weight of the binder.
