Structure and Design of the ZAB
Schematic illustration and operation principle of the ZAB with multiphase electrolytes: a hydrophilic PTFE membrane divides the solution into homogeneous and heterogeneous phases, and the redox of zinc is carried out in the heterogeneous phase; the OER electrode releases oxygen in heterogeneous phase during charge process, and the ORR electrode consumes oxygen in homogeneous phase during discharge process.
