Abstract:
A negative electrode for a lithium secondary battery includes: a negative electrode active layer provided on at least one surface of a negative electrode current collector, and including a negative electrode active material; and a coating layer disposed on the negative electrode active layer. The coating layer contains silicon-containing particles, aluminum-containing particles and a dispersant, and a volume resistance of the coating layer is about 1.0×10−4 Ω·cm to 1.0 Ω·cm.
