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, wherein the composite electrolyte comprises
a first electrolyte comprising a lithium salt and a first organic solvent, and
an interconnected network structure disposed on a surface of the anode current collector, the interconnected network 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, and
a liquid-impermeable ion-conductive composite membrane disposed between the cathode and the composite electrolyte, wherein the liquid-impermeable ion-conductive composite membrane comprises at least one of a solid ionic conductor or a composite comprising the solid ionic conductor and a non-ionic conductor.
