Abstract: A hybrid solid-state electrolyte layer for use in an electrochemical cell is provided. The hybrid solid-state electrolyte layer includes a polymeric material, a ceramic material, and an interfacial material adhering the polymeric material and the ceramic material. The interfacial material includes a branched copolymer that includes dopamine and a second monomer. The second monomer forms a polymeric moiety in the copolymer that is the same or similar to the polymeric material. In certain variations, the polymeric material defines a polymeric layer, the ceramic material defines a ceramic layer, and the interfacial material defines an interfacial layer that is disposed between the polymeric layer and the ceramic layer. In other variations, the polymeric material defines a polymeric matrix, the ceramic material defines a plurality of ceramic particles dispersed in the polymeric matrix, and the plurality of ceramic particles are coated with the interfacial material.

Abstract: An anodeless electrochemical cell is provided that includes a positive electroactive material layer and a patterned current collector. The patterned current collector includes a non-conductive substrate and a conductive network disposed over a surface of the non-conductive substrate. The surface of the non-conductive substrate defines a first surface area, and a perimeter of the conductive network defines a second surface area. The second surface area covers greater than 90% of the first surface area. The conductive network includes a framework having plurality of pores, such that the conductive network has a porosity greater than or equal to about 20 vol. % to less than or equal to about 95 vol. %. During a charging event, the pores are configured to receive deposited lithium metal. The anodeless electrochemical cell further includes a separator between the positive electroactive material layer and the patterned current collector.
