Developing chemistries for positive electrodes with large specific capacities and high operating potentials is highly desirable for aqueous zinc batteries. Here, authors report a reversible Se electrode that undergoes ZnSe↔Se↔SeCl4 reaction, combined with Br− /Brn – redox couple as Se revitalizer to enhance cycling performance.
