Exploring Sustainable and Scalable Materials for Energy Storage and Harvesting Applications

Dear Colleagues,

The growing demand for renewable energy solutions has driven research into advanced materials that enable efficient energy harvesting, storage, and conversion. This Special Issue invites research articles on novel materials for energy harvesting (e.g., solar cells, piezoelectric/triboelectric nanogenerators, thermoelectrics) and storage (e.g., sustainable batteries, supercapacitors, phase-change thermal systems). Contributions should address material design, performance optimization, and integration into eco-friendly technologies.

This Special Issue seeks studies employing advanced characterization techniques such as electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), SEM, and XRD to elucidate structural, conduction, and stability properties under varied operational conditions. This issue aims to advance the development of high-performance energy systems through innovative materials and analytical methodologies. Theoretical, experimental, and computational studies are welcome.

In this Special Issue, original research articles and reviews are welcome. Topics may include, but are not limited to, the following:

• Solar energy harvesting/photovoltaic materials;
• Piezoelectric energy harvesting;
• Triboelectric nanogenerators (TENGs);
• Thermoelectric generators (TEGs);
• Sustainable battery materials;
• Supercapacitors and hybrid energy storage;
• Thermal energy storage (TES)/phase change materials (PCMs);
• Electrochemical characterization of energy materials;
• Integrated energy storage-harvesting systems.

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. Processes 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 2400 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.
