Dear Colleagues,

With the fast advancement of contemporary technology, the need for energy storage devices is growing daily. Despite the availability of sources, most renewable energy sources have significant challenges in storing energy for an extended period. Supercapacitors have been regarded as one of the most progressive and efficient technologies among numerous energy storage systems. Supercapacitors may store an electrical charge in an electric double layer at the electrode–electrolyte interface. The global market for SCs was anticipated to reach $1.5 billion in 2017, and demand is expected to more than triple in future years. Many new electrode materials have been developed recently to provide high-performance supercapacitors with a high energy density, increased cycle stability, and improved capacitance. Various synthetic methodologies have been established to manufacture various supercapacitors, such as flexible, wearable, hybrid-type supercapacitors, micro-supercapacitors, etc. These supercapacitor devices will likely play a vital role in the world of electronics shortly.

This open access Special Issue will include original research, mini-reviews, research prospects, and complete state-of-the-art articles on the most recent advancements in supercapacitor technology. This Special Issue focuses on novel synthetic methodologies, electrode materials, and device manufacturing processes for supercapacitor applications. It also focuses on providing the most recent cutting-edge breakthroughs in supercapacitor technology. We welcome all researchers to contribute their work on supercapacitor synthesis methodologies and manufacturing techniques. 

Topics include, but are not limited to:

• Electrode materials;
• The most recent 2D materials;
• Nanomaterials, including composite and hybrid;
• Electrochemical behavior of functional nanomaterials;
• Advanced synthetic methods;
• Binder-free electrodes for supercapacitors;
• Energy materials;
• Chalcogenides (including Se, S, and Te) for supercapacitors;
• Layered double hydroxide (LDH) for supercapacitors;
• Functional telluride-, nitride-, phosphide-, and sulfide-based nanomaterials;
• Carbon nanoparticles generated from biomass;
• Materials with microporous and mesoporous pores;
• Functional carbon materials (graphene, graphene oxide, carbon nanotubes, nanoionics, and fullerenes).

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. Journal of Composites Science 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 1800 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.
