Hydrothermal formation and electrochemical property of Ag_1.8 Mn_8 O_16 microcrystals for Li-ion battery cathode application

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.
