1. A method of making a solid-state lubricant coating on a substrate, the method comprising:
making a homogeneous slurry comprising powder of an oxide of a metal, graphene, and a polymeric binder;
coating a substrate with the homogeneous slurry; and
drying the slurry on the substrate, resulting in a solid lubricant coating on the substrate,
wherein the weight percent of graphene is in the range of 70 to 90 in the resulting solid lubricant coating and wherein the polymeric binder is one of polyvinylidene difluoride, polyethylene oxide, and polyvinyl acetate.
