Advanced Functional Materials for Energy Harvesting and Storage Devices, Volume II

Dear Colleagues,

Very recently, the fabrication of energy-harvesting, storage, and conversion systems, including nanogenerators, supercapacitors, lithium-ion batteries, solar cells, photo/electro-catalysts, etc., has received remarkable attention and, in recent years, become a hot research topic. Up to now, numerous researchers have utilized different functional materials, including two-dimensional (2D) materials, MXenes, metal oxides, metal phosphides, metal sulfides, metal–organic frameworks, etc., as the active materials for energy-harvesting, storage, and conversion systems. However, there are still many challenges to overcome, such as the low output voltage of piezoelectric nanogenerators, the poor output current density of triboelectric nanogenerators, the poor power density of supercapacitors, the poor cyclic stability of lithium-ion batteries, the low conversion efficiency of solar cells, etc. Accordingly, this Special Issue seeks to showcase research papers and review articles that focus on novel developments in energy-harvesting, storage, and conversion systems.

Topics of interest include, but are not limited to:

• Triboelectric nanogenerators;
• Pyroelectric nanogenerators;
• Piezoelectric nanogenerators;
• Supercapacitors;
• Lithium-ion batteries;
• Solar cells.

We look forward to receiving your submissions!

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-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.
