We report results from an aqueous quinone-bromine redox flow battery in which the negative electrode is a substituted quinone/hydroquinone couple and the positive electrode is bromine/hydrobromic acid. The redox active materials, which can be very inexpensive, contain no metals. Consequently, the cell appears to be a very attractive candidate for inexpensive, large-scale electrical energy storage.

We will report the performance of a small flow battery based on this couple.
