Composite binder containing carbon nanotube and lithium secondary battery employing the same
Provided is a nanocomposite binder for an electrode mix of a secondary battery, comprising carbon nanotubes in a photo- and/or thermo-polymerizable material or polymer, or a mixture thereof; and a lithium secondary battery comprising the same.The carbon nanotube-containing composite binder according to the present invention and a lithium secondary battery comprising the same employs a novel nanocomposite, prepared by combination of carbon nanotubes with a conventional binder material, as a binder of an anode. As a result, the present invention provides advantages such as improved conductivity of the anode due to decreased electrical resistance of the binder, and enhanced mechanical properties of the binder and thereby being capable of preventing the separation of an anode active material layer from a current collector due to volume changes occurring upon charge/discharge cycles.
