Recent Advances in Energy Storage Devices Based on Laser-Processed Carbon Nanomaterials

Dear Colleagues,

One of the most common materials capable of simultaneously meeting the requirements of rich structural morphology, highly active surfaces, high electrical/thermal conductivity, and strong chemical stability is carbon materials at the nanoscale, known as carbon nanomaterials, such as graphene, carbon nanotubes, and carbon nano-fibers/rods/spheres. However, the traditional processes of preparing carbon nanomaterials usually require complex experimental setups, harsh synthesis conditions, and lengthy processing times. The emergence of laser processing techniques, as reported in 2014 by James M Tour, has made it possible to efficiently manufacture carbon nanomaterials on a large scale. By regulating laser types and parameters, local high temperatures up to 3000 K can be achieved in the laser–material interaction areas. The rapid heating and cooling characteristics (>10⁶ K s⁻¹) of laser processing can create unusual reaction conditions for preserving structural defects and/or heterostructures.

The present Special Issue on Nanomaterials aims to present the current state of the art in the application of laser-processed carbon nanomaterials in energy storage devices, particularly in micro-scale devices such as supercapacitors and batteries. The electrochemical properties of laser-processed carbon nanomaterials are closely linked to the choice of carbon precursors, laser types, and parameters. Therefore, discovering new carbon precursors and laser processing techniques is crucial. In the present Special Issue, we invite contributions from leading groups in the field with the aim of providing a balanced overview of the current state-of-the-art advances in this discipline.

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. 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 2900 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.
