A magnesium oxide (MgO) coating strategy is proposed for improving the cobalt-free high-nickel LiNiMnO cathode. It is revealed that a MgO coating can stabilize reversible Ni/Ni redox and suppress structural degradation. The MgO coated LiNiMnO exhibits a promising capacity retention of 66.

Due to the advantages of resource abundance and low reduction potential of calcium, calcium-ion battery (CIB) becomes one of the potential candidates for energy storage devices. Prussian blue analogues (PBAs) are promising cathode materials for CIB, but they suffer from limited capacity and poor cyclability. Herein, a new PBA cathode NiCoHCF is designed with electrochemical active Co and inactive Ni.
