Dear Colleagues,

The march of global warming, caused by excess greenhouse gas emissions, is hoped to be met, at least in the mid-term, by powerful electrochemical energy storage systems. Abandoning combustion engines will greatly cut our dependencies on fossil fuels. Systems, based on mobile lithium ions, are currently the most advanced batteries with which most of the portable devices and electric vehicles are powered. Although we have witnessed remarkable advances in the last decade, further progress in lithium-ion battery technology, based on liquid electrolytes, might crest in the future.

All-solid-state lithium-ion batteries with solid electrolytes represent a next-generation technology. Turning away from the highly flammable liquid electrolytes is expected to greatly improve safety and longevity, i.e., to reduce aging processes. Compared with the conductivity of liquid electrolytes, ion transport in solid electrolytes is usually some orders of magnitude slower than that in liquid or gel-type organic electrolytes. Fortunately, over the last couple of years, some breakthroughs have been reported in the search for suitable materials, which are characterized by ultrafast ion dynamics and negligible electronic transport, and has reached an unprecedented level.

This Special Issue aims to present the latest findings on all aspects related to solid-state battery research, i.e., it is not only restricted to systems with lithium as an ionic charge carrier. Manuscripts presenting studies of the following topics are highly welcome: (i) synthesis and characterization of solid electrolytes (ion dynamics and transport properties), (ii) electrochemical performance and stability, (iii) interfacial phenomena and charge transfer resistances, (iv) bulk-type and thin film batteries, and (v) new processing techniques.

It is my pleasure to invite you to submit a manuscript (full papers, communications, or reviews) for the Special Issue, “Solid-State Batteries”.

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 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.
