Special Issue Information

Dear Colleagues,

Finding new materials for energy storage applications is a topic that is still of utmost importance in the field of energy science. Supply risks have set the challenge of replacing well known compounds electrode and electrolyte compounds using cobalt free systems, and also to develop new battery chemistries for use in stationary energy storage. In this respect, inorganic fluorides and oxyfluorides have been shown to be interesting alternative materials for a variety of battery systems. These are not limited to the well-studied lithium ion batteries, but also include sodium and fluoride ion batteries. In all these systems, they can work as active electrode materials, with further applications as solid electrolytes in the case of fluoride ion batteries.

This Special Issue of Applied Sciences aims at covering a broad variety of aspects of inorganic fluorides and oxyfluorides for battery applications, covering the synthesis, electrochemical properties and/or battery characteristics of this class of materials.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Magnesium oxide, generally applied as a filler in high-temperature cells (with an electrolyte melting point above 250 °C), was modified with magnesium fluoride to improve its mechanical and electrical properties. Samples containing 10 and 25 mol.% MgF2 were prepared and calcined at 500, 600, and 700 °C. They were characterized by low-temperature nitrogen adsorption and X-ray diffractometry (XRD). Moreover, the electrolyte absorption, mechanical strength of pellets made of filler and electrolyte, and volume of unfilled spaces were determined. It was shown that the introduction of MgF2 in the amount of 10 and 25 mol.% results in a considerable decrease in the surface area of the initial MgO, which testifies to the covering of MgO by the formed fluoride. However, no new crystalline phases were formed as concluded from the XRD analysis. The pellets consisting of electrolyte and MgF2/MgO filler (the electrolyte + 40 wt.% of the filler) had a higher mechanical strength compared to bare MgO filler. In particular, they outperformed MgO in the ionic conductivity of molten electrolyte. The latter was almost three times as high as that of MgO filler, when the filler containing 25 mol.% MgF2 was employed. The aforementioned properties of MgF2/MgO materials predispose them for use as fillers in high-temperature cells. Full article
