Abstract
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. The electrochemical cell includes an aqueous electrolyte solution in which the anode and the cathode are disposed, wherein the aqueous electrolyte solution is configured to transport the multivalent cations between the anode and the cathode.
