“…5(a)), in the pristine state, two large peaks are observed at 139.0 and 143.9 eV and two small peaks are observed at 136.6 and 141.5 eV. Four peaks are indexed to the Pb 4f7/2 and 4f5/2 peaks of PbF2 (Pb 2+ ) and those of metallic Pb, respectively [30,31]. Upon changing from the pristine state to the fully discharged state, peaks indexed to metallic Pb increase and peak intensities indexed to PbF2 decrease.…”

“…The electronic states of Pb in the electrode during the discharge and charge processes were investigated through XPS (Figure ). Two peaks, both assigned to Pb 2+ (PbF 2 ), are observed at 139.0 and 143.9 eV in the pristine state (bottom in Figure ) . In addition to the peaks assigned to Pb 2+ (PbF 2 ), peaks indexed to Pb metal were observed at 136.6 and 141.5 eV in the partially discharged state (100 mAh g –1 , second from bottom in Figure ) .…”

Lead fluoride (PbF2) is a promising electrode material for fluoride shuttle batteries (FSBs) owing to its high theoretical capacity (219 mAh g–1). In this study, the discharge and charge capacities of a PbF2 electrode were measured using a bis[2‐(2‐methoxyethoxy)ethyl] ether containing cesium fluoride and triphenylborane as an electrolyte. A high specific capacity was maintained during both the discharge and charge processes in the first cycle, but the capacity decreased from the first charge process to the following discharge process. To clarify the electrochemical reaction mechanism, the dissolution and change in the electronic state of Pb at the PbF2 electrode during the discharge and charge processes were evaluated via atomic absorption spectrometry (AAS) and X‐ray photoelectron spectroscopy (XPS). The results obtained from AAS and XPS indicated that Pb was formed during the discharge process. Conversely, the formation of PbF2 and dissolution of Pb coexisted within the wide range of charge process. The PbF2 could react in the following cycle, but the dissolved Pb was unable to contribute to the following discharge/charge reaction. Therefore, after the initial charge process, the capacity decreased.

“…Huang et al started investigating the synthesis of LnF 3 in 2004. 35 The first synthesis made wire-shaped LnF 3 , nanosize in two dimensions but several hundred nanometres long in the other. This method was interesting as the synthesis first made very long, thin wires of NH 4 LnF 4 (Ln ¼ Nd, Sm, Eu, Gd and Tb) which were then calcined to form LnF 3 .…”

The requirement for narrow emission profiles and systems that do not include metals perceived to be cytotoxic, has led to an increase in the reports on rare-earth (Ln) materials, with fluoride-based materials in particular attracting attention. This class of compounds includes rare-earth fluorides (LnF(3)), rare-earth oxyfluorides (LnOF) and alkali metal rare-earth fluorides (MLnF(4), where M represents an alkali metal). Here we will describe the main reactions outlining key developments in roughly chronological order.
