Electrochemical Energy Storage and Conversion: Materials, Devices and Advanced Technologies

Dear Colleagues,

Safe and low-priced energy availability is crucial to technology innovation leading to the improvement of our daily quality of life. Nowadays, over 80% of global energy demand is derived from fossil fuels (coal, oil and natural gas). A direct consequence of the use of fossil resources is the increase in carbon emissions: current levels of CO₂ in the atmosphere have reached 420 ppm. The global energy demand is projected to further increase faster due to the growing world population and expanding industrialization. In addition, we have already used over 50% of the global carbon budget (the ability of the environment to assimilate carbon without increasing the average global temperature by 2 °C). Extrapolating the current trends, we will exceed this budget by about 2050. As a result, major concerns have been raised over the climate change associated with the use of fossil fuels and the related CO₂ and greenhouse gases emissions. The world population need to satisfy their energy demand with different sources than fossil fuels because the environmental consequences such as climate change will be catastrophic. It is more important now than ever to develop sustainable green and renewable energy conversion and storage technologies with no detrimental effects on the environment.

Between the renewable and sustainable sources of energy, the ones most frequently considered are solar, wind, tidal and hydropower. However, due to the intermittent nature of these energy sources, these technologies are only operative for some part of the day. Therefore, alternatives to the use of these renewable sources of energy are necessary. In this sense, electrochemical ways of energy conversion and storage such as fuel cells, electrolyzers, batteries and supercapacitors play a crucial role.

This Special Issue on “Electrochemical Energy Storage and Conversion: Materials, Devices and Advances Technologies” focuses on the latest research and developments in this area. We are pleased to invite you to submit articles within the scope of Physical Chemistry, Materials Science and Chemical Engineering aimed at developing new electrocatalysts and devices for the Electrochemical Energy Storage and Conversion. Original research and review articles are welcome. Research areas may include (but be not limited to) the following:

• Electrocatalysis
• Interfacial Electrochemistry
• Physical Methods for the Study of Electrode Surfaces and Interfaces

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. Processes is an international peer-reviewed open access monthly 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 2400 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.
