Among them, it has good results in the application of cathode materials in charge and discharge batteries. It has a stable three-dimensional structural framework and a uniform pore structure that can accommodate most alkali metal cations. It has the characteristics of low cost, long life and environmentally friendly production process. In this study, Na-FeFe Prussian blue was prepared by co-deposition method, and four samples with different particle sizes were prepared at 25°C, 50°C, 70°C and 85°C titration temperature respectively. Using X-ray diffraction to analyze the lattice structure of the sample and understand the chemical composition, the particle sizes of 12 nm, 21 nm, 37 nm and 54 nm were prepared according to different titration temperatures, and silver nanoparticles were added to the cathode electrode piece. Prussian blue and silver nanoparticles were uniformly mixed, coated and dried, and then pressed to form a battery, and the influence of the battery charge and discharge efficiency was discussed. The 85°C titration temperature of 54 nm was added with different proportions of silver nanoparticles, the proportions of which were 14%, 25% and 35%, respectively, to test the battery charge-discharge cycle performance analysis. In addition, it also discusses the use of different charging and discharging currents for testing, and discusses the performance stability and impact of different currents on the battery. |
