Composition for Forming Electrode Protective Layer, Electrode for Lithium Secondary Battery and Lithium Secondary Battery Comprising the Same

Abstract

Provided are a composition for forming an electrode protective layer for a lithium secondary battery, comprising a polythiophene-based conductive polymer that exhibits PTC (positive temperature coefficient) characteristics, and porous conductive carbon particles having a plurality of pores with a diameter of 10 to 300 nm formed therein, which not only suppresses heat generation or ignition caused by external impacts, etc., and thus has excellent stability, but also makes it possible to provide electrodes and batteries having excellent conductivity and rate characteristics, and an electrode for a lithium secondary battery and a lithium secondary battery comprising the same.

Dependencies are inferred from the claim text.
