Abstract
A battery structure with a cathode, an electrolyte, and a lithium metal anode is coated with a composite coating including a mixture of a polymer and a reinforcing fiber. The cathode and the lithium metal are held apart by a porous separator soaked with the electrolyte. The reinforcing fiber is dispersed in the polymer matrix. The composite coating is porous or non-porous. The composite coating conducts lithium ions. The reinforcing fiber is chemically functionalized.
