Special Issue Information

Dear Colleagues,

It is evident that growing societies will consume more energy, and the availability of energy will allow populations to proliferate. Consequently, population growth leads to an increased demand for raw minerals and energy resources, but their supply cannot be provided at the same rate. Up-to-date technologies contain materials that are becoming more finely intermixed because of the broadening palette of elements used, and this results in some boundaries for recycling. The recovery and separation of individual elements (materials) from the complex systems require complex energy-consuming solutions, with many hazardous chemicals used. Significant pressure is brought to bear on the improvement of separation and recycling approaches by the need to balance sustainability, efficiency, and environmental impacts.

The ionic liquids, also known as molten salts and future solvents, are endowed with unique features that already have had a cutting-edge impact on promising science and technologies.

This Special Issue aims to address the current challenges associated with the energy-efficient design, recovery, recycling, and separation of valuable materials employing ionic liquids, including, but not limited to:

  • Recovery and separation of rare earths and other valuable metals
  • Electrodeposition from ionic liquids
  • Recycling of waste (bio, plastic, electronic, etc.)
  • IL-based electrolytes for battery technologies
  • Environmental impact of ionic liquids

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. Energies 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.

Population growth has led to an increased demand for raw minerals and energy resources; however, their supply cannot easily be provided in the same proportions. Modern technologies contain materials that are becoming more finely intermixed because of the broadening palette of elements used, and this outcome creates certain limitations for recycling. The recovery and separation of individual elements, critical materials and valuable metals from complex systems requires complex energy-consuming solutions with many hazardous chemicals used. Significant pressure is brought to bear on the improvement of separation and recycling approaches by the need to balance sustainability, efficiency, and environmental impacts. Due to the increase in environmental consciousness in chemical research and industry, the challenge for a sustainable environment calls for clean procedures that avoid the use of harmful organic solvents. Ionic liquids, also known as molten salts and future solvents, are endowed with unique features that have already had a promising impact on cutting-edge science and technologies. This review aims to address the current challenges associated with the energy-efficient design, recovery, recycling, and separation of valuable metals employing ionic liquids. Full article
