Title:
GRAPHENE-CURRENT COLLECTOR-INTEGRATED NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/107860
Kind Code:
A1
Abstract:
The present invention relates to a graphene-current collector-integrated negative electrode for a lithium secondary battery, which inhibits growth of a dendrite on a lithium negative electrode to provide stability and a lifespan characteristic, and a method for manufacturing the same. A graphene-current collector-integrated negative electrode according to the present invention includes a metal foam and a graphene layer having a three-dimensional structure in which domains attached to the metal foam and including a nanoscale flat portion and a nanoscale corrugation portion are continuously arranged. In addition, lithium is formed on the graphene layer.
