Abstract: Disclosed is an electrode comprising an aliphatic nitrile compound, wherein the aliphatic nitrile compound is coated on a surface of the electrode or is incorporated into the electrode active materials. A lithium secondary battery having the electrode is also disclosed. The lithium secondary battery has excellent safety so as to prevent ignition and explosion generated when the internal temperature of the battery is increased due to the heat emission caused by the reaction of an electrolyte with a cathode and the structural collapse of a cathode occurring upon overcharge. Additionally, it is also possible to prevent ignition and explosion when the battery is exposed to high temperature due to an increase in temperature resulting from heating or local short circuit caused by physical impacts. Further, it is possible to solve the problems of an increase in viscosity and degradation in battery performance at a low temperature occurring when an aliphatic nitrile compound is used as an additive for electrolyte.
