Special Issue Information

Dear Colleagues,

Most research today has the overall objective of contributing to the development of energy vectors as electricity and hydrogen. In this regard, the study and the development of systems, processes and materials for electrochemical production, conversion and storage of energy is crucial to decrease fuel consumption and emissions and support concomitantly, the use of renewable sources for distributed generation and transport. Many research activities have been performed in field of energy to develop innovative devices to satisfy the increasing market demands. High- and low-temperature fuel cells and electrolyzers for the production and re-use of hydrogen can be the focus of this Special Issue. Also, with regard to hydrogen, much is being done for the development of materials and processes for its storage and reuse. The purpose of this Special Issue is to publish high-quality research papers as well as review articles addressing recent advances on systems, processes, and advanced materials for electrochemical production, conversion and the storage of energy by mean hydrogen. Original, high-quality contributions that are not yet published or that are not currently under review by other journals or peer-reviewed conferences are sought.

Dr. Alessandro Dell'Era
Guest Editor

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. Materials 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 2600 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.

In this study, lithium was recovered from LiFePO4 (LFP) cathode active materials through a two-step thermal process combining hydrogen reduction and chlorination roasting. Hydrogen reduction was conducted while varying temperature and holding time to promote oxygen removal from LFP and induce phase separation into Li3PO4 and iron phosphides (FeP and Fe2P). Based on stoichiometric assessment using the degree of LFP decomposition and the reduction in oxygen moles, the optimal hydrogen-reduction condition was determined to be 900 °C for 1 h. Subsequently, CaCl2 was selected as an appropriate chlorination agent using thermodynamic considerations, and the hydrogen-reduced product was reacted with CaCl2 to convert Li3PO4 into water-soluble LiCl. The mass of LiCl produced was quantified as a function of reaction temperature. Water leaching enabled the separation of LiCl from the insoluble residues, resulting in an overall lithium recovery of 71.7%. Full article
