Title:
CURRENT COLLECTOR CAPABLE OF EFFECTIVELY SUPPRESSING UNCONTROLLABLE GROWTH OF DENDRITIC CRYSTAL OF LITHIUM METAL BATTERY, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/210673
Kind Code:
A1
Abstract:
The present disclosure provides a current collector capable of effectively suppressing uncontrollable growth of the dendritic crystal of a lithium metal battery, and a preparation method therefor and an application thereof. The current collector is a copper sheet having a recessed structure. Preparation of a negative electrode by using the current collector having the specific structure can effectively suppress uncontrollable growth of the dendritic crystal of a lithium metal battery, avoid piercing the battery separator, and improve the performance of the lithium battery.
