Type: article
Abstract: Prussian blue has significant advantages as a cathode material for sodium-ion batteries. First of all, it has good electrochemical stability and reversibility, and can maintain high energy efficiency and cycle stability in multiple charge and discharge cycles. Secondly, Prussian blue has rich sodium storage capacity and high specific capacity, which can effectively improve the energy density and power performance of the battery. The preparation process of Prussian blue is relatively simple and the material cost is low. But Prussian blue also has several major drawbacks as a cathode material for sodium-ion batteries. Its low conductivity can lead to poor performance at high current densities. Long-term cyclic charge and discharge process capacity attenuation is serious, affecting the life of the battery. In addition, the structure of Prussian blue may change during charging and discharging, which is poor in stability, limiting its ability to operate stably for a long time. In this research, the performance of Prussian blue is effectively improved through the improvement of manufacturing process and chemistry, and its advantages are more obvious.
