In this article, Ag1.8Mn8O16 microcrystals assembled from nanosphere building blocks were successfully fabricated via a one-pot hydrothermal route using silver nitrate and potassium permanganate as raw materials. The particles were characterized by X-ray powder diffraction (XRD), energy dispersive X-ray microanalysis (EDX), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM), cyclic voltammogram, galvanostatic charge–discharge and Nyquist plane plot. Ordinary differential equations (ODEs) and the electrode kinetics were used to investigate the synthesis and electrochemical activity. The as-prepared Ag1.8Mn8O16 microspheres reveal the highest reversible discharge capacity ∼1468 mAh even after 100 cycles in the potential range of 3.4–4.2 V and the best cycling stability. |
