Negative electrode containing electrode protective layer and lithium secondary battery comprising the same

Abstract

A negative electrode including an electrode protective material and a lithium secondary battery including the negative electrode, wherein the negative electrode containing the protective material can inhibit the growth of lithium dendrite on the surface of the electrode, effectively transfer lithium ions to the lithium metal electrode and has an excellent ion conductivity, and thus the protective layer itself including the protective material does not act as a resistive layer, overvoltage is not applied during charging and discharging, thereby preventing degradation of the performance of the battery and ensuring stability when driving the battery.
