Abstract
The present invention relates to a composite separation membrane for a lithium secondary battery, having an excellent effect of improving the life time and safety of a battery and a lithium secondary battery including the membrane. The composite separation membrane includes a porous base layer; a heat-resistant layer formed on one side or both sides of the porous base layer; and a fusion layer formed on an outermost layer. The heat-resistant layer includes inorganic particles connected and fixed by binder polymers, and the fusion layer includes crystalline polymers in the form of particles having a melting temperature of 100° C. or higher.
