Special Issue Information

Dear Colleagues,

The increasing demand for energy and the electrification of mobility in modern society have increased the demand for higher energy density, power density, and safety standards as well as lower costs. Consequently, lithium ion batteries, ubiquitously applied from portable electronics to transportation or grid storage applications, now do not meet the requirements for many applications.

Moreover, the low abundancy and uneven distribution of lithium sources are increasing the cost of lithium-based technologies. With these driving forces, many research groups around the world are focusing on increasing the power and energy densities of batteries, either lithium based or with different chemistries. The next-generation energy storage systems, so called “beyond lithium ion batteries”, promise higher levels of theoretical energy or power density, although each chemistry has its own challenges, and the real numbers are lower than the thoretical ones. In order to overcome these challenges and achieve higher power and energy densities, novel electrode architectures have been proposed to enhance the cycling performance of electroactive materials, rate capabilities, and electrode–electrolyte interactions, among other.

This Special Issue of Electronic Materials is a Joint Special Issue with Materials, it aims to present recent advances in the design and synthesis of nanoarchitectured electrode materials, focusing on novel chemistries and nanostructuration strategies applied to positive or negative electroactive materials for metal-ion batteries and capacitors and metal-air and lithium-sulfur batteries. Authors are invited to submit relevent full papers, short communications, and reviews for inclusion.

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. Electronic Materials is an international peer-reviewed open access quarterly 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 1000 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.

Aero-eutectic graphite can be defined as a new light material with hierarchically structured porosity. It is obtained from the solidification of gray cast irons, followed by the dissolution of the ferrous matrix by an acidic sequence. The result is a continuous and interconnected network of graphite sheets with varied dimensions randomly oriented. X-ray diffraction characterization has revealed graphite crystallographic planes (002), (100), (101), (102) and (004), while the surface area measured by BET and Langmuir methods has been determined in the order of 90 m2 g−1 and 336 m2 g−1, respectively. The process of obtaining eutectic aero-graphite also allows the deposit of Cu nanofilms and TiC particles. Aero-eutectic graphite has been tested as cathode in Li–O2 batteries as it has been prepared, without the addition of binders or conductive carbons, showing an appropriate contact with the electrolyte, so that the oxygen reduction and evolution reactions may develop satisfactorily. In the discharge-charge galvanostatic tests, the battery accomplishes 20 complete cycles with area capacity limited to 1.2 mAh cm−2. Full article
