    • 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.
    • 本发明提供一种用于二次电池的电极混合物的纳米复合粘合剂,其包含光 - 和/或热可聚合材料或聚合物中的碳纳米管或其混合物; 和包含该锂二次电池的锂二次电池。 根据本发明的含碳纳米管复合粘合剂和包含该纳米复合材料的锂二次电池使用通过碳纳米管与常规粘合剂材料组合制备的新型纳米复合材料作为阳极的粘合剂。 结果,本发明提供了优点,例如由于粘合剂的电阻降低导致阳极的导电性提高,粘合剂的机械性能的提高,从而能够防止阳极活性物质层与集电体分离 由于充放电循环时发生体积变化。
