| Abstract Scope |
Nanoscale oxide-based negative electrodes are of great interest for rechargeable metal ion batteries due to their high energy density, power density and enhanced safety. Here, we report a case study on mesoporous TiO2 nanoparticle negative electrode with uniform size and varying crystallinity to investigate the trend in the electrochemical properties of oxide-based nanoscale negative electrodes with varying crystallinity. Mesoporous solid spherical TiO2 nanoparticles with a uniform particle size and varying crystallinity, i.e., amorphous TiO2 (A-TiO2), partially crystalline TiO2 (PC-TiO2) and fully crystalline TiO2 (FC-TiO2) nanoparticles were studied. The effect of crystallinity in the mesoporous TiO2 nanoparticle electrodes was investigated under quasi steady-state and off equilibrium states through electrochemical characterizations as well as synchrotron pair distribution function analysis. |
