NANOWIRE COMPOSITIONS AND METHODS THEREOF

Disclosed is a nanowire composition that includes nanowires comprising aluminum fluoride (AlF) (AFNWs). The aluminum fluoride comprises α-phase AlF. In some implementations, an average diameter of the AFNWs is in a range of 100 to 500 nm, an average length of the AFNWs is in a range of 100 to 1000 μm, and an average aspect ratio of the AFNWs is in a range of 1000 to 1×10. An AFNW membrane, an anode-interlayer component comprising AFNWs, and a lithium metal battery incorporating the anode-interlayer component are also disclosed. Related methods of making AFNWs, an AFNW membrane, an anode-interlayer component, and a lithium metal battery are also disclosed.
