Effect of Temperature and Particle Size On the Structure and Electrochemical Properties of Two-dimensional V$_{\mathrm{2}}$O$_{\mathrm{5\thinspace }}$Nanosheets.

Atomically thin two-dimensional nano materials exhibit unique features for charge storage including ultra high accessible surface area and the ability to better accommodate structural changes than bulk material. These two-dimensional materials potentially can provide charge storage with enhanced reversibility, capacity, rates and cycling. Analysis of the size and heat treatment of hydrated two-dimensional vanadium pentoxide (V$_{\mathrm{2}}$O$_{\mathrm{5}}$\textbullet nH$_{\mathrm{2}}$O) was done to determine the effect on the electrochemical properties of the material. Characterization of V$_{\mathrm{2}}$O$_{\mathrm{5}}$\textbullet nH$_{\mathrm{2}}$O was done via x-ray diffraction, scanning electron microscopy, and Raman spectroscopy. Initial results of the electrochemistry suggest smaller two-dimensional particle size indicates better electrochemical performance.
