Introduction
Lithium fluoride (LiF) is a very important multi-valent ionic liquid material, who mobility and flexibility have attracted much significant attention in the past few decades for its potential applications in a variety of energy areas, such as battery and fuel cell technologies, solar cells and various electrochemical systems. Track fundamental understanding of the chemical and physical properties of LiF is esntial to fully understand its fascinating potential.
X-ray diffraction (XRD) is an important tool for studying the structure of various materials. Containing a large number of atomic lattices in its unit cell, LiF crystal has rich XRD diffraction peaks, which are mainly attributed to its high degrees of crystallinity, good local order and strong covalent bonds. XRD data can be ud to provide insight into the LiF crystalline structure and determine the LiF lattice constants. Thus, LiF XRD diffraction peaks are ud to characterize its structures and properties.
XRD peaks of LiF
The XRD spectrum of LiFl consists of three distinct diffraction peaks: a first sharp peak (FSDP) at 2 θ = 5.81° ɑ, a cond sharp peak (SSDP) at 2 θ = 8.20° and a third sharp peak (TSDP) at 2 θ = 10.84°, e Fig.1.

The FSDP can be attributed to the 100 plane, indicating a (100) face orientation of LiF crystal. The SSDP is given by the 110 plane, showing a (002) face orientation, while the T
SDP originates from the 211 plane, with a (101) face orientation. XRD peaks at 2θ = 16.36°, 18.87°, 24.09° and 31.99° were obtained from the 111, 011, 311 and 003 planes, respectively.
The LiF lattice constants are a = 4.661 Å, b = 4.661 Å, c = 3.167 Å and the lattice space group is Pnma, which implies that the LiF crystal structure belongs to the monoclinic system. The lattice constants obtained from the XRD data are generally consistent with tho obtained from other experimental methods [4], further confirming the structure and properties of LiF.
Conclusion
In conclusion, XRD is an effective technique for analyzing the structure of LiF. XRD peaks obrved in the LiF spectrum can be ud to determine the LiF lattice constants, to provide insight into the LiF crystalline structure and to characterize its properties. By understanding the properties of LiF, the potential of LiF for many energy-related applications can be explored in an easy and preci way.
