 This research has developed a novel rechargeable aqueous zinc ion battery, ZIB, with metal organic framework, MOF, materials as both the cathode and anode. The MOF materials were designed to store zinc ions while also preventing the zinc from being stripped off the anode during charging and discharging. The resulting battery showed improved performance compared to existing batteries, with a higher capacity and longer life cycle.
