High-Performance Supercapacitors

Dear colleagues,

Energy storage is a key topic for research and industry which has recently been gaining more and more attention. Specifically, supercapacitors are electrochemical storage and conversion devices, which combine the high energy-storage capability of conventional batteries with the high-power delivery capability of conventional capacitors. Being able to achieve higher power and a longer life cycle than conventional dielectric capacitors and batteries, supercapacitors have been developed to provide power pulses for a large variety of applications and are readily applicable in portable electronic devices, automobile vehicles, backup power supplies, and stationary power stations. Unfortunately, the major challenge for supercapacitors is insufficient energy density, which limits the supercapacitor’s wider applications. Thus, developments are required in supercapacitor technology and supporting electronics, combined with reductions in costs, which may revolutionize everything from large power systems to consumer electronics. Recently, there have been numerous efforts focusing on the development of new electrode materials and electrode configuration to develop high-performance supercapacitors, to improve the performance of state-of-the-art supercapacitors to meet the stringent requirements for the applications mentioned above, as well as many other advanced applications not discussed here. In order to benchmark the state of research in this area at this time, Energies invites papers for a Special Issue dedicated to recent development in high-performance supercapacitors. Topics on any supercapacitor-related aspects are encouraged, with specific attention to the following topics of both electrical-double-layer supercapacitors (EDLCs) and pseudo capacitors.

Topics of interest for publication include but are not limited to:

• Electrode materials development
• New configuration for hybrid supercapacitors
• Supercapacitor technologies, processes, and materials
• Electrolytes development
• Experimental techniques for analyzing supercapacitors
• Cycle stability and self-discharge analysis
• Supercapacitor integration and combinations with other energy storage solutions
• Novel applications including portable devices, automobiles, stationary power stations

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. 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 2600 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.
