Special Issue Information

Dear Colleagues,

To mitigate the issues of climate change and economic dependence on fossil fuels, the transition towards universal and illimited renewable energy sources has become unavoidable. The transport of energy from production site to consumers as well as the intrinsic intermittence of renewables require the use of suitable energy carriers and their efficient storage. Electricity and hydrogen are complementary energy vectors, particularly adapted to this task. They can be efficiently stored: electricity in electrochemical batteries, and hydrogen in the form of reversible compounds, i.e., hydrides. Moreover, they are complementary and can be converted from one into the other using electrolysers and fuel cells.

This Special Issue entitled “New Intermetallics and Hydride Materials for Hydrogen Storage and Battery Applications” will be devoted to original works and reviews focusing on the latest findings on materials based on metals, intermetallics, and hydride compounds for battery devices and the hydrogen energy chain. Both experimental and computational studies are welcome. This Special Issue of Materials will cover but will not be limited to the following topics:

  • Metals, intermetallics, and complex hydrides for hydrogen storage and compression
  • Hydrides for on-board hydrogen storage and production
  • Metallic membranes for hydrogen purification
  • Intermetallics for Ni-MH batteries
  • Metals, intermetallics, and hydrides as anodes of Li-ion batteries
  • Intermetallics as anodes of mono- and multi-valent rechargeable batteries
  • Hydrides as solid-state electrolytes of mono- and multi-valent rechargeable batteries

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. 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.

Using a new class of (BH4)− substituted argyrodite Li6PS5Z0.83(BH4)0.17, (Z = Cl, I) solid electrolyte, Li-metal solid-state batteries operating at room temperature have been developed. The cells were made by combining the modified argyrodite with an In-Li anode and two types of cathode: an oxide, LixMO2 (M = ⅓ Ni, ⅓ Mn, ⅓ Co; so called NMC) and a titanium disulfide, TiS2. The performance of the cells was evaluated through galvanostatic cycling and Alternating Current AC electrochemical impedance measurements. Reversible capacities were observed for both cathodes for at least tens of cycles. However, the high-voltage oxide cathode cell shows lower reversible capacity and larger fading upon cycling than the sulfide one. The AC impedance measurements revealed an increasing interfacial resistance at the cathode side for the oxide cathode inducing the capacity fading. This resistance was attributed to the intrinsic poor conductivity of NMC and interfacial reactions between the oxide material and the argyrodite electrolyte. On the contrary, the low interfacial resistance of the TiS2 cell during cycling evidences a better chemical compatibility between this active material and substituted argyrodites, allowing full cycling of the cathode material, 240 mAhg−1, for at least 35 cycles with a coulombic efficiency above 97%.
