Polymer Gels in Electrochemistry

Dear Colleagues,

Electrolytes play a crucial role in energy storage devices such as batteries and supercapacitors. However, the use of liquid electrolytes leads to the possibility of their leakage. In turn, solid electrolytes ensure safety and high mechanical properties, but at the same time, have a very low conductivity. Therefore, gel electrolytes seem to be the solution. They present high ionic conductivity while remaining solid and preventing leakage. Thanks to the considerable modification possibilities regarding their composition, it is possible to regulate their ionic conductivity and mechanical properties depending on the requirements. Therefore, there is great potential for their application in energy storage devices. Depending on the nature of the applied electrolyte, it is possible to synthesize the hydrogels containing a water solution of different salts, ionogels containing ionic liquids and organogels containing salt dissolved in organic solvents. Each group of gel electrolytes is characterized by different properties and could be use in different electrochemical applications.

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 250 words) can be sent to the Editorial Office for assessment.

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. Gels 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 2100 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.
