“…The films had a Li:Al ratio of 2.7:1, as determined with ICP-MS and carbon, silicon and oxygen impurities were below the XPS detection limit. The films had an ionic conductivity of 7.5 × 10 −6 S/cm at room temperature [146], which is similar to the first reports from the literature on thermally evaporated amorphous Li 3 AlF 6 films [12,13]. Interestingly, changing the pulsing ratio to three subcycles of AlF 3 and one LiF resulted in the same metal ratio in the as-deposited film as the pulsing ratio of 1:1, suggesting a similar conversion reaction as we have seen in our experiments on LiF [151] and Li 3 AlF 6 [139].…”

“…These materials have been deposited by thermal evaporation and fast quenching, resulting in amorphous thin films. The increased ionic conductivity in these mixtures is attributed to the formation of amorphous intermediate phases with high coordination numbers for lithium, such as in the Li3AlF6 phase [13]. Even more complicated fluoride mixtures have been studied as well [12,14,[54][55][56], such as the LiF-AlF3-ScF3 system, which can reach similar conductivity values as the pure Li3AlF6 [12].…”

“…However, some examples of potential electrolyte materials can be found in the literature. Li3AlF6, a stoichiometric ternary of LiF and AlF3, has been reported to show high ionic conductivities of the order of 10 −6 S/cm in thin film form [12][13][14]51]. In addition, milling Figure 6.…”

“…this ternary fluoride with LiCl has been reported to lead to high conductivities [52]. Other fluorides that also show high conductivities when mixed with LiF include NiF2, VF3, CrF3 and YF3 ( Figure 7) [13,53]. These materials have been deposited by thermal evaporation and fast quenching, resulting in amorphous thin films.…”

“…However, by using the same nanofabrication methods as for anodes, these materials could provide a new, interesting class of lithium-ion battery electrode materials. Additionally, fluorides have also been reported to show high lithium-ion conductivities, making them possible solid electrolytes for all-solid-state thin film batteries [12][13][14].…”

Lithium-ion batteries are the enabling technology for a variety of modern day devices, including cell phones, laptops and electric vehicles. To answer the energy and voltage demands of future applications, further materials engineering of the battery components is necessary. To that end, metal fluorides could provide interesting new conversion cathode and solid electrolyte materials for future batteries. To be applicable in thin film batteries, metal fluorides should be deposited with a method providing a high level of control over uniformity and conformality on various substrate materials and geometries. Atomic layer deposition (ALD), a method widely used in microelectronics, offers unrivalled film uniformity and conformality, in conjunction with strict control of film composition. In this review, the basics of lithium-ion batteries are shortly introduced, followed by a discussion of metal fluorides as potential lithium-ion battery materials. The basics of ALD are then covered, followed by a review of some conventional lithium-ion battery materials that have been deposited by ALD. Finally, metal fluoride ALD processes reported in the literature are comprehensively reviewed. It is clear that more research on the ALD of fluorides is needed, especially transition metal fluorides, to expand the number of potential battery materials available.

This article covered several topics related to the solid electrolyte interphase (SEI) in lithium‐based batteries. The reactivity of fresh lithium to typical air and electrolyte components is firstly discussed. The catalysis effect on SEI formation is explored, focusing on the surface dependence of reduction potential and selectivity of reduction product. Mechanical effect on SEI formation is introduced, including the chemical–mechanical coupling during the cycling and the SEI composition change with electrode fracture. Ionic conductivity, solubility, and mechanical properties of SEI are summarized and discussed. In addition, critical technical challenges during the surface characterization of SEI are elaborated, such as ex situ sample preparation, beam damage, and sputtering effect. With the main objective to explore and resolve challenges in the SEI field, this article is concluded with future prospects.
