Special Issue Information

Dear Colleagues,

The increasing demand for low-cost energy conversion and storage technologies which can increase the utilization of intermittent renewable energy sources such as sunlight has brought attention to redox flow batteries (RFBs) and photoelectrochemical (PEC) energy conversion processes. For instance, organic RFBs are slowly emerging as a low-cost energy storage solution which exploits structurally tailorable and naturally abundant organic redox materials. In particular, this diversity of choices in redox species makes it possible to match the energy levels of the semiconductors, which is currently the most attractive aspect of the PEC rechargeable RFB systems. Consequently, the PEC RFBs emerge as an alternative all-in-one technology for the simultaneous conversion and storage of solar energy. The ability to decouple power and capacity and the rapid kinetics of electrochemical reactions is another key advantage of RFBs.

However, the comprehensive implementation of the RFB to this promising PEC battery system has been limited by RFB lifetime, low solar-to-chemical conversion efficiency, and low photovoltage, which limits discharge capacity. In this Special Issue of Energies, we address the recent advances and breakthroughs in RFB systems in aqueous and non-aqueous electrolytes for efficient solar energy storage. We invite original research articles, short communications, as well as review, comment, and prospective articles addressing issues related to RFBs and PEC redox flow batteries, with a special focus on their development or application, including but not limited to new redox species, lifetime, PEC electrodes, electrolytes, catalysts, membranes, modelling, characterization techniques, system optimization, and industrial implications.

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. Energies 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 2000 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.
