摘要: A method for making a lithium salt film includes heating a substrate, spraying a mixture with a spray nozzle onto the substrate to form a precursor film, and annealing the precursor film to form the lithium salt film. The lithium salt film has a thickness of about 400 nm to about 100 pm. The spray mixture includes a first precursor comprising a lithium ion, a second precursor comprising an anion, and a solvent.
