This gathering was intended to facilitate exchange of ideas and collaborations among experts, engineers and beginners in the field of electrochemistry. The joint 4-day symposium was organized by the Association of South-East European Electrochemists (ASEEE) http://www.aseee.eu and gathered 176 participants from 23 countries, giving in total 5 plenary talks, 10 keynote talks, 65 oral presentations and 64 poster presentations. Also, the Satellite Student Symposium with 14 contributions was associated to the main symposium event. The Book of abstracts can be downloaded from here: http://www.aseee.eu/userfiles/rse- 7/Book-of-abstracts.pdf. The conference was dedicated to the memory of late Professor Zdravko Stoynov (1936–2017), a world distinguished Bulgarian electrochemist and one of the founders of the regional cooperation of electrochemists, established in 2008 through RSE–SEE chain of conferences. The conference was aimed to highlight advances and new findings in electrochemistry area and its impact on technology development. In the year of Nobel prize–electrochemistry winners who developed Li-ion batteries and created a rechargeable world, it is of special importance to emphasize that the present symposium topics were: Batteries and electrochemical energy storage, Corrosion science and protection, Electrochemical engineering, Electroanalytical chemistry and sensors, Organic electrochemistry and bio-electrochemistry, Physical electrochemistry, Materials and electrochemical processing and General topics. This broadness of topics is reflected in this issue with papers not only on the basics of energy storage and energy storage devices such as batteries and fuel cells, but also on electrochemical sensing technologies, electrolytic production of metals, electrochemical synthesis for various purposes and corrosion inhibition. http://www.jese-online.org/ http://www.aseee.eu/ http://www.aseee.eu/userfiles/rse-7/Book-of-abstracts.pdf http://www.aseee.eu/userfiles/rse-7/Book-of-abstracts.pdf J.
