Negative Electrode For Lithium Secondary Battery, Having Improved

Negative Electrode For Lithium Secondary Battery, Having Improved Safety Against Internal Short Circuit, Lithium Secondary Battery Comprising Same, And Lithium Secondary Battery System For Same

Abstract: The present invention relates to a negative electrode for a lithium secondary battery, a lithium secondary battery comprising same, and a lithium secondary battery system for same. The negative electrode for a lithium secondary battery comprises silicon-containing particles and aluminum-containing particles, having specific components, and thus can have a predetermined volume resistivity. Accordingly, a lithium secondary battery comprising the negative electrode allows a predetermined current to leak, while having appropriate insulation on the surface of the negative electrode, when an internal short circuit occurs, and thus can prevent the internal short circuit from causing a meltdown and/or rapid heat generation in the lithium secondary battery.
