Nanomaterials for Supercapacitors

Dear Colleagues,

With the increasing demand of clean and renewable power technologies, supercapacitors have received extensive interest in the research and several practical applications have been realized in relation to their remarkable power density, rapid charge/discharge capability, and excellent long-term-cycling performance; therefore, they are regarded as one of the most promising electrochemical energy-storage devices. Electrode material, as an example, plays a key role in the final electrochemical performance. In comparison to bulk electrode material, nanoscale material (nanomaterial) exhibits a larger specific surface area with abundant active sites, which is beneficial for electrolyte penetration, electron transfer, and redox reactions too; therefore, an improved electrochemical performance may be expected. At present, a large quantity of nanomaterials have been used for the production of supercapacitors, such as carbon-based materials (e.g., graphene, carbon nanotubes, and carbon cloth), conductive polymers, and transition metal oxides (phosphide and hydroxides), as well as some emerging materials, including Mxene, metal–organic frameworks, and metal dichalcogenides. Therefore, all these electrode materials can be utilized in the construction of supercapacitor devices.

The current Special Issue focuses on the latest advances in nanomaterial-based supercapacitors with an enhanced performance. This includes, but is not limited to, the exploitation of new electrode materials, structure and morphology designs, doping, and composite formation. The Special Issue aims to promote the performance of electrode materials and expand the applications of supercapicitors in the field.

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 250 words) can be sent to the Editorial Office for assessment.

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. Nanomaterials 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.
