With this communication we demonstrate, that these systems can be successfully used at school and in higher education. The focus is put upon the use of compounds found in bark and peat as well as humic acids. http://pubs.sciepub.com/wjce/7/2/14/wjce-7-2-14.pdf Redox-Flow-Batteries renewable energy organic batteries natural products
