Special Issue Information

Dear Colleagues,

Polycrystalline solid oxide electrolytes are increasingly attracting research attention from the viewpoint of their utilisation as energy materials for various electrochemical devices, from lithium ionic batteries to solid oxide fuel cells. The success in the application of such electrolytes largely depends on the level of their electrical conductivity, which, in turn, is regulated by the bulk and grain boundary conductivities. Although the conductivity values can be quite precisely determined for simple (unipolar- and single-phase) systems, the investigation of multi-phase compositions and/or multi-conducting materials frequently represents a challenging task. A correct separation of the bulk and grain boundary conductivities provides not only an improved understanding of the nature and structure of grain boundaries, but also enables the optimisation of the transport properties of electrolytes. The attainment of both of these goals is extremely important for the design of efficient and high-performance electrochemical systems. This Special Issue aims to provide a unique platform for exchanging opinions and discussing recent achievements in the analysis of “complicated” solid oxide materials, with a particular focus on their grain boundary transportation features.  Original research papers, state-of-the-art reviews, and short communications of the theoretical and experimental character are welcome.

Manuscript Submission Information

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 papers will be 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. Crystals is an international peer-reviewed open access monthly 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 1600 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.
