“…74-2352) appeared in BiOCl when further discharged to 0.01 V, which can be attributed to a conversion reaction. Such similar behavior was also reported in the sodiation of other metal oxychloride [9]. When the cell was recharged, all new phases disappeared and the peak shifted back due to the extraction of Na þ .…”

Mg‐based batteries, which use the Mg2+ shuttle, theoretically offer several advantages compared to the Li technology, such as higher theoretical volumetric capacity (3833 mA h cm−3) of the Mg‐metal anode, the possibility to be safely handled in air, and dendrite‐free electrodeposition. In this study, vanadium oxychloride was employed as an electrode material in a Mg‐based battery. As the cell delivered just 45 mA h g−1 in the first cycle, we tried to improve the delivered capacity through preliminary cycling of the VOCl electrode with Li. The strategy is based on the ability of VOCl to expand its interlayer spacing upon intercalation of ions or molecules within them. In fact, a VOCl electrode with expanded interlayer spacing should facilitate the intercalation of Mg2+, thus leading to higher specific capacities. The Li pretreatment was able to promote the specific capacity by a factor of four (170 mA h g−1) after the first discharge at 298 K. Over 130 mA h g−1 was retained at 5 mA g−1 after 70 cycles. Structural and electrochemical characterization was carried out by means of galvanostatic charge/discharge tests, cyclic voltammetry, ex situ X‐ray photoelectron spectroscopy, X‐ray diffraction, transmission electron microscopy coupled with energy‐dispersive X‐ray spectroscopy, and electron energy loss spectroscopy. Inductively coupled plasma optical emission spectrometry was used to determine the concentration of lithium in the electrode.

“…Further cathode reports also proposed the use of VOCl,, which performed very well in a series of different battery systems such as the widely used LIBs, sodium ion batteries, and Mg ion batteries . VOCl seems to have a wide range of electrochemical behavior depending on the anode used, and the following mechanisms have been proposed for the different systems (Table ).…”

Chloride Ion Battery Review: Theoretical Calculations, State of the Art, Safety, Toxicity, and an Outlook towards Future Developments

2017

Batteries in which chloride ions act as shuttles have only been under investigation for a few years, but already several publications have dealt with this topic. In this review, we extensively report for the first time the state of the art, as well as research on chloride ion batteries and chloride conduction. In addition, we present a theoretical screening along with calculations of the capacities and volumetric and gravimetric densities, as well as an analysis of safety and toxicity. At the end, possible future approaches are evaluated.
