A molecular dynamics (MD) simulation has been carried out to explore the microstructure and diffusion pathway in amorphous vanadium pentoxide (V2O5) materials at room temperature ambient pressure. We showed that simulated model is a mix of basic units VO5 VO6 connected each other via 2 or 3 bridging oxygens. In model, there exist regions without atoms (cavity) form clusters channels. found 87% ...
