“…Although the mechanism of the conversion reactions of the transition metal oxides is not fully understood, it is believed that the electrochemically driven size confinement of the nanoscale metal particles is the key point to enhance their electrochemical activities toward the formation/decomposition of Li 2 O. 328 The conversion reactions of the transition metal nitrides, 329 fluorides 330 and phosphides 331 have been reported. Nanomaterials exhibit the desirable advantages such as improved lithium ion diffusion rate in the solid phase of the host compound; enhanced reaction rate caused by larger interface between the electrode and the electrolyte due to a high surface area and porosity of the nanostructures; and potential new reactions that are not possible with the bulk materials.…”

Over the past decades, there have been many projections on the future depletion of the fossil fuel reserves on earth as well as the rapid increase in green-house gas emissions. There is clearly an urgent need for the development of renewable energy technologies. On a different frontier, growth and manipulation of materials on the nanometer scale have progressed at a fast pace. Selected recent and significant advances in the development of nanomaterials for renewable energy applications are reviewed here, and special emphases are given to the studies of solar-driven photocatalytic hydrogen production, electricity generation with dye-sensitized solar cells, solidstate hydrogen storage, and electric energy storage with lithium ion rechargeable batteries.

“…These results indicate that the FeF 3 obtained in this study could be used as cathode material, even though the reversible capacity of this electrode material is not sufficient at the present stage. In addition, improvement of the capacity is expected by optimization of the preparation process in order to synthesize single phase FeF 3 . This optimization could be accomplished using techniques such as flux treatment or after annealing treatment; the obtained samples mixed with a small amount of PTFE and heat again at 500°C for 1 min to remove the carbon in the obtained FeF 3 sample and to oxidate from Fe 2+ (FeF 2 ) to Fe 3+ (FeF 3 ).…”

A fluoride electrode material for lithium-ion batteries, FeF 3 , was synthesized by a novel solid-state reaction method using polytetrafluoroethylene (PTFE) as a fluoride source instead of HF. FeF 3 was obtained as the main phase according to the XRD patterns of the samples prepared in the present study. Furthermore, the synthesized FeF 3 particles were nanosize. The initial discharge and charge capacities of the FeF 3 sample were 387 and 293 mAh/g, respectively, in the 4.51.0 V region.

“…Recently, interesting progress has been made in this research area. For example, BiF 3 , FeF 2 and FeF 3 have been studied extensively as cathodes using nanocomposites of the metal fluorides and conductive carbon [38,40]. Using nanocomposites with carbon can not only help with the volume change but also with the inherently low electrical conductivity of fluoride materials.…”

Metal Fluorides as Lithium-Ion Battery Materials: An Atomic Layer Deposition Perspective

2018

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.
