Abstract

Disclosed herein relates to an electrode for a lithium secondary battery including an insulating layer. The insulating layer is formed on a first insulating layer containing a first binder and on the first insulating layer, and includes a second insulating layer containing inorganic particles and a second binder, wherein the first binder is PVDF (Polyvinylidene fluoride), and the second binder is SBR (styrene butadiene rubber). Accordingly, the insulating layer of the present invention is excellent in wetness adhesion and electrical safety.
