Title:
LITHIUM METAL NEGATIVE ELECTRODE COMPOSITE CURRENT COLLECTOR, PREPARATION METHOD THEREFOR AND LITHIUM ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/047737
Kind Code:
A1
Abstract:
Disclosed in the present application is a lithium metal negative electrode composite current collector, comprising a metal substrate layer and a transition metal boride layer at least provided on the surface of the metal substrate layer. By means of the transition metal boride layer, the lithium metal negative electrode composite current collector of the present application can effectively improve the wettability and the binding force of the negative electrode lithium metal layer and the current collector, and can form atomic-scale lattice matching with lithium metal, such that lithium metal atoms are guided to be uniformly deposited on the surface of the current collector, lithium dendritic growth is inhibited, and the safety and stability of the battery are effectively improved.
