摘要：

The spiny spherical MnCO3@MnO2 cathode material for aqueous zinc ion batteries was designed and constructed. Electrochemical test results revealed that, the spiny spherical MnCO3@MnO2 cathode material had an initial discharge capacity of 598.2 mAh/g at a current density of 0.2 A/g. As the current density increased with the gradient and then decreased to 0.2 A/g, the specific capacity remained at 541.5 mAh/g, indicating the superior performances compared to that of MnCO3. This research showed that this spiny spherical MnCO3@MnO2 has distinctive structural characteristics and can easily embed zinc ions, demonstrating a competitive cycle stability in aqueous systems.
