Dear Colleagues,

Thermal energy storage (TES) allows the storage of excessive heat, aiding in the efficient use and provision of thermal energy, wherever there are mismatches of time, temperature, power, or location between the energy generation and applications. The application of novel phase change materials (PCMs) enables thermal energy storage in the form of combined sensible and latent heat, providing a larger heat storage capacity within a limited volume. PCMs also feature nearly constant temperature behavior during melting and solidification, and this benefits efficient system thermal management. However, the remaining challenge aligned with PCMs is its low thermal conductivity. Continuous research efforts on improving heat storage efficiencies are meaningful for extending their practical applications. The past two decades have witnessed the extensive research and applications surrounding the TES with PCMs, including the smart system design, heat transfer enhancement, accurate heat storage modelling, synthesis and characterization of novel materials, micro/nano encapsulation, and recently the involvement of artificial intelligence. Hence, with this Special Issue, we would like to take this opportunity to provide a concentrated platform and gather the latest related research in this rapidly evolving field.

This Special Issue on “Thermal Energy Storage with Phase Change Materials” aims to curate novel advances in the development and application of phase change materials to address longstanding challenges in effective thermal energy storage. Topics include, but are not limited to, the following:

• Development and characterization of innovative phase change materials;
• Effective heat transfer enhancement in phase change materials;
• Micro/Nano technologies for phase change materials;
• Application of artificial intelligence in thermal energy storage and phase change material design;
• Experiments and numerical simulations for small–medium scale thermal energy storage units;
• Fundamental study on the melting and solidifying processes of phase change materials;
• Novel applications of phase change materials for heat storage in robotics, space, electronics, energy, manufacture and biomedical fields.

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. Processes 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 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.
