ABSTRACT

Here we report the utilization of inorganic-organic hybrid (IOH) as a new type of cathode material for aqueous Zn-ion batteries. The IOH possessing a unique lattice-water-rich layered structure achieves high long-term cycling stability (81.5% capacity retention over 1500 cycles) and ultrafast charging capability (～90% state of charge about 1 minute).
