Magnesium metal has a high theoretical volume capacity and abundant reserves. ion battery is theoretically secure eco-friendly. In recent years, magnesium attracted wide attention expected to become competitive energy storage candidate in the next generation. However, due large polarization effect slow migration kinetics of ions, ions are hard insert/desert cathode materials, resulting poor cycle rate performance. CoHCF, typical Prussian blue analog, an open frame structure double REDOX sites, it regarded as for rechargeable battery. Herein, Ni-doping method was utilized improve performance CoHCF. Compared with original maximum specific discharge Ni-doped CoHCF at 50 mA/g charging discharging current increased from 70 mAh/g 89 mAh/g, cyclic improved. These improvements result fact that electrode reaction process changes diffusion-driven reaction-driven. The more stable, lattice during Mg2+ (de-)intercalation smaller. This study can provide reference development analogs materials batteries.
