▎ 摘　　要

NOVELTY - Liquid metal-containing coating, where the coating is a liquid metal-containing composite powder coated on the surface of a substrate to form a uniform liquid metal-containing coating, where the composite powder containing liquid metal is a mixture of 30-90 pts. wt. liquid metal and 10-70 pts. wt.solid filler. USE - The coatings useful in one dimensional, two-dimensional, and three-dimensional conductive materials or anode-free lithium metal batteries (claimed). ADVANTAGE - The coating has excellent mechanical stability and scratch resistance on the surface of the substrate. The method for preparing coating is simple to operate, and can realize processing on the substrate with different material and shape. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing coating by using flowable metal or composite powder.
