Lithium Secondary Battery With Improved Safety

Abstract: The present invention relates to an anode for a lithium secondary battery and a lithium secondary battery comprising same. The anode for a lithium secondary battery has advantages of: i) having a high energy density by containing a silicon-based material as an anode active material; and ii) having improved safety against an internal short-circuit of the lithium secondary battery by including an individual mixture layer composed of a silicon-based material with a relatively low electrical conductivity at the outermost region of a multi-layered anode mixture layer to thereby lower the current amount at the time of occurrence of an internal short-circuit and thus reduce the heating value.
