Abstract
In this article, Ag_1.8 Mn_8 O_16 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 Ag_1.8 Mn_8 O_16 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.
