Current Developments in the Biochar Sector

Dear Colleagues,

Biochar has been an important research issue worldwide in recent years. This is evidenced by the numerous multidisciplinary research studies and the significant increase in the number of scientific articles in international journals. One of the main applications of biochar is its use as a renewable fuel. Carbonates can be burned or co-fired in combined heat and power plants. They provide an alternative solution to conventional fossil fuels with an attractive calorific value. Other interesting energy applications of biochar include electrocatalysis, fuel cells, supercapacitors, and batteries.

Electrochemical energy storage technology is crucial for the sustainable development of autonomous and portable electronic devices. Reports indicate that the use of carbonaceous materials from biomass can greatly simplify the manufacturing process of electrodes for supercapacitors and batteries. Electrochemical energy storage devices, such as batteries and supercapacitors, have become popular due to their ability to store energy and release it when needed. However, it is important to look for new and sustainable electrode materials to increase the efficiency of such devices sustainably. Carbon materials are widely used as substrates for supercapacitor electrodes, but they have disadvantages such as high costs and a large carbon footprint. An alternative solution may be the use of biochar from biomass, but its application in the electrochemical sector requires improving its electrochemical properties, particularly increasing its specific surface area, through treatments such as activation and doping.

In this Special Issue, authors are encouraged to submit papers that cover high-quality novel research, as well as review studies on recent developments in the biochar sector development, particularly in relation to 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. 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.
