Special Issue Information

Dear Colleagues,

Due to the depletion of fossil fuels and escalating environmental pollution concerns, environmentally friendly renewable energy storage and conversion technologies have garnered significant attention from researchers. The advancement of high-performance energy materials has emerged as a pivotal focus in the evolution of energy conversion and storage technologies. Consequently, researchers have been actively investigating the nanoscale interactions between energy and matter to address this challenge. These explorations have contributed to an enhanced grasp of low-dimension material control and design, paving the way for the development of more efficient energy conversion/storage devices such as batteries and supercapacitors.

To highlight the recent advances in this field, Materials is launching a virtual Special Issue, entitled “Low Dimensional Materials for Batteries and Supercapacitors”, focusing on batteries and supercapacitors.

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.

In order to effectively recover Li from cathode active materials of lithium-ion batteries, model samples of LiCoO2 mixed with polyvinylidene fluoride (PVDF) were calcined at temperatures of 350–700 °C under an Ar or air atmosphere. Complete Li recovery was achieved by calcining the model sample at 400 °C under an Ar atmosphere, followed by water leaching. Additionally, to immobilize PVDF-derived F, an impurity in Li purification, we explored the use of calcium compounds (Ca(OH)2 and CaCO3) and a layered double hydroxide in both dry and wet processing methods. In the wet process, F was fixed by adding Ca(OH)2 to an aqueous LiF solution containing 1000 ppm of F. We confirmed that 98.6% of F was successfully removed from the solution after repeated fixation procedures. Furthermore, the unreacted Ca in the solution was separated and removed as CaCO3 by concentrating the solution. Full article
