Electrochemical cell with melanin electrode

An electrochemical cell includes an anode configured to produce multivalent cations during a discharge process, and a cathode comprising a catechol-bearing melanin. The cathode is configured to reversibly oxidize a catechol of the catechol-bearing melanin into a quinone by an extraction of the multivalent cation during a recharge process and reduce the quinone to the catechol by an insertion of the multivalent cation during the discharge process. ...
