Green Composite Electrolytes and Electrodes for Energy Storage and Conversion, Volume II

Dear Colleagues,

In recent years, there has been extensive research on the development of high-performance electrochemical devices which can generate and store energy at a low cost following green and sustainable approaches. Cost-effective and eco-friendly electrolytes from renewable sources represent a promising substitute for synthetic materials. The necessity of a green chemistry has significantly increased throughout the world, as we need to reduce environmental degradation associated to the quick increase of global energy demand from portable electronics to electric vehicles and also large-scale energy storage devices for smart grids.

The Special Issue on “Green Composite Electrolytes and Electrodes for Energy Storage and Conversion, Volume II” will address advances in the synthesis, processing, fabrication, characterization, and properties of green materials for possible application in energy storage and conversion. For instance, fuel cell systems contribute to sustainability and environmental issues thanks to the chemistry and thermodynamics of hydrogen electrochemical oxidation, which increases energy conversion efficiency and reduces pollutant emissions to zero. Microbial fuel cells have intrinsic green and eco-friendly aspects because they use organic and residual materials for their operations, but actual electrodes (synthetic carbon-based nanomaterials) and membranes (nafion proton exchange polymer membrane) are still based on non-green raw materials and resources, and valid alternatives should be developed. Supercapacitors have also attracted great attention owing to their unusually high energy density that may enable the use of new handheld devices, hybrid vehicles, and alternative energy sources. The materials typically used to store energy, for example, activated carbon, are unsustainable and expensive. Green aspects of these energy conversion/charge storage devices are really challenging when in comes to designing truly green devices with regard to all the components. Contributions aiming to collect novel green materials used in fuel cell membranes (for example, natural polysaccharides, such as chitosan derivative), supercapacitors (for example, biochar) and in any other energy storage and conversion devices are welcome.

This Issue collects papers from research groups with diverse backgrounds to discuss all aspects of this topic. Both original research and comprehensive review papers are solicited on all types of green materials with theoretical or experimented application in energy storage and conversion devices.

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. Journal of Composites Science is an international peer-reviewed open access monthly journal published by MDPI.
