Special Issue Information

Dear Colleagues,

A supercapacitor is a high-capacity capacitor with much greater capacitance values than other capacitors, which bridge the gap between electrolytic capacitors and rechargeable batteries. They typically store 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerate many more charge and discharge cycles than rechargeable batteries. Interest in supercapacitors has been growing due to their moving towards more environmentally friendly and safer materials, and present an opportunity to solve energy challenges with a promising future vision.

This Special Issue is dedicated to highlighting significant findings in the field of composite materials for supercapacitors. Supercapacitors have emerged as a new type of energy storage device that is able to provide relatively larger energy and power densities. The aim of this Special Issue is to share interesting and promising works among researchers, particularly advanced electrode design based on composite materials. State-of-the-art composite electrode materials including carbon/carbon, carbon/metal oxide, carbon/polymer, and other novel composite material systems can be covered. We will also consider advanced composite materials in supercapacitors and intermediate devices between them. The paper topics can range from the preparation and the fundamental properties of materials, their electrochemical characterization, and novel device structures.

It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome.

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. Materials 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.

In this work, we report a feasible fabrication of NiCo2S4 nanotree-like structures grown from the Ni nanoparticle (NP)-doped reduced graphene oxides (Ni-rGO) by a simple hydrothermal method. It is found that the presence of Ni NPs on the surface of the rGOs initiates growth of the NiCo2S4 nanotree flocks with enhanced interfacial compatibility, providing excellent cyclic stability and rate performance. The resulting NiCo2S4/Ni-rGO nanocomposites exhibit a superior rate performance, demonstrating 91.6% capacity retention even after 10,000 cycles of charge/discharge tests. Full article
