Anode for lithium secondary battery comprising mesh-shaped insulating layer, and lithium secondary battery comprising same
Abstract:
The present invention relates to a negative electrode for a lithium secondary battery including a mesh-type insulating layer, and a lithium secondary battery including the same, and in particular, to a negative electrode for a lithium secondary battery including a mesh-type insulating layer formed on one surface of the lithium metal layer and having pores, and a lithium secondary battery including the same. The lithium secondary battery using the negative electrode induces a lithium dendrite precipitation and removal reaction inside pores of the insulating layer suppressing local lithium metal formation on the lithium metal surface and forming a uniform surface, and cell volume expansion may be suppressed therefrom, and forms a support layer on a passivation layer formed at the beginning preventing deintercalation and collapse of the passivation layer, and may enhance a battery lifetime by minimizing dead lithium while suppressing additional side reactions with a liquid electrolyte.
