Special Issue Information
Dear Colleagues,
Electrochemical supercapacitors have garnered significant attention as next-generation energy storage devices due to their rapid charge–discharge capability, long cycle life, and high-power density. Recent innovations in nanomaterials engineering have played a pivotal role in overcoming the intrinsic limitations of conventional capacitive materials. The development of advanced electrode materials—such as graphene derivatives, carbon nanotubes, MXenes, transition metal oxides, and conductive polymers—has particularly enabled significant improvements in both energy and power densities. Furthermore, with the introduction of hybrid and asymmetric device configurations, the energy–power trade-off has successfully been addressed, combining electric double-layer capacitance with faradaic redox reactions. Emerging fabrication techniques, including electrospinning, atomic layer deposition, and 3D printing, offer precise control over nanoscale architectures, leading to enhanced ion accessibility and charge transport pathways. This research contributes to the growing body of work aimed at designing high-performance, flexible, and solid-state supercapacitors for applications in portable electronics, electric vehicles, and grid-level energy storage. The continued integration of nanotechnology with electrochemical systems holds considerable potential for advancing sustainable and efficient energy storage solutions.

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. Micromachines 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 2100 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.
