Title:
LITHIUM SECONDARY BATTERY NEGATIVE ELECTRODE AND PREPARATION PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/240795
Kind Code:
A1
Abstract:
A lithium secondary battery negative electrode and a preparation process therefor. The lithium secondary battery negative electrode comprises: a substrate (1), which is an electrically conductive substrate; a one-dimensional columnar structure (2), which grows on one or two surfaces of the substrate and is perpendicular to a plane where the substrate is located, the one-dimensional columnar structure being an electrically conductive structure; an active material layer (3), which is located on the substrate and is perpendicular to the plane where the substrate is located, the active material layer covering an outer surface of the one-dimensional columnar structure; and a protective layer (4), which is located on the substrate and is perpendicular to the plane where the substrate is located, the protective layer covering an outer surface of the active material layer.
