High-Performance Supercapacitors

Dear Colleagues,

Lightweight, high-performance, and environmentally friendly energy storage and generation devices, such as those based on hydropower, solar energy, and wind energy in addition to lithium ion batteries and supercapacitors (SCs), are one of the key solutions to relieving the heavy burden on the current energy infrastructure, modern electronic industry, and the environment. The Paris Climate Change Agreement has fueled the development of low carbon footprint-based energy storage and conversion devices in an effort to maintain the global average temperature increase at below 2 °C. Batteries are employed as electrical energy storage device in electric vehicles (EVs) owing to their high energy density. However, batteries suffer from longer charging time, low power density, and poor shelf and cycle life. In comparison to conventional batteries, SCs offer higher power density, amenability for large-scale production, faster charge–discharge rate along with remarkable cycling stability, rendering them potential energy storage device contenders in EV.

On the other hand, the energy density of commercialized SCs suffers from relatively low values compared to rechargeable batteries and does not satisfy the ever-increasing energy requirement of next-generation electronic devices. The most crucial factor for the preparation of efficient SCs are the selection of materials and fabrication of high-performance electrode materials with high electrical conductivity to ensure rapid charge–discharge. Another promising solution to enhance the energy density of SCs is to increase the specific capacitance and output voltage.

This Special Issue is focused on bringing together innovative developments and synergies in the field of high-performance SCs.

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-anonymized 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.
