Special Issue Information

Dear Colleagues,

Research on new, reliable, renewable, and sustainable sources of energy has paved the way for the design and development of novel energy conversion and storage devices. Energy storage, conversion, and utilization based on energy-efficient technologies such as windmills, solar cells, and fuel cells, have become the need of the day in meeting the basic requirements of man in modern life. Many of these renewable and sustainable energy-efficient technologies mainly rely on environmentally friendly energy storage devices like batteries and supercapacitors (SCs). As far as a single-cell supercapacitor is concerned, there are three distinct classes of system configurations based the composition of electrode materials:symmetric, asymmetric, and hybrid supercapacitors, even though the distinction between asymmetric and hybrid supercapacitors remains controversial. Symmetric supercapacitors, as the name suggests, are composed of identical materials on both electrodes, whether it is a carbon-based EDLC electrode or a pseudocapacitive electrode. The majority of commercial devices are asymmetric, based on activated carbon,  in combination with pseudocapacitor or hybrid electrode materials based on transition metal oxides, conducting polymers or other carbonaceous materials. Hence, symmetric and asymmetric supercapacitors are one of the most advanced area of research in case super capacitors. This Special Issue invites original research articles from advanced area of symmetric and asymmetric supercapacitors.

Potential topics include, but are not limited to, the following:

  • Symmetric/asymmetric supercapacitor system design considerations
  • Carbon-based electrode materials used for supercapacitors
  • Different electrode material synthesis methods for symmetric/asymmetric supercapacitors
  • Metal oxide electrode materials used for symmetric/asymmetric supercapacitors
  • Functionalization of electrodes used for symmetric/asymmetric supercapacitors
  • Applications of symmetric/asymmetric supercapacitors in various fields
  • Asymmetric hybrid supercapacitors
  • Composite hybrid supercapacitors rechargeable battery-type hybrid supercapacitors

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. Symmetry 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 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.
