1. A charged lithium metal battery comprising:
a cathode comprising a cathode current collector and a cathode active material layer on the cathode current collector;
an anode current collector, wherein the anode current collector is a mesh current collector;
a composite electrolyte between the cathode and the anode current collector; and
a solid electrolyte disposed between the composite electrolyte and the cathode;
wherein the composite electrolyte comprises a first electrolyte comprising a lithium salt and a first solvent and
an interconnected network structure disposed on a surface of the anode current collector, the interconnected structure comprising a plurality of connected metal particles, each metal particle comprising a core of at least one of lithium or lithium metal alloy and lithium from the lithium salt is electrodeposited on a surface of the core of the metal particles, wherein the electrodeposited lithium connects the metal particles to form a layer.
