Hierarchical hollow Li4Ti5O12 urchin microspheres with ultra-high specific surface area of over 140 m2·g–1 have been successfully synthesized and have a high specific capacity of 120 mA·h·g–1 at 20 C. Electron energy loss spectroscopy at different charge–discharge stages reveals the charge–discharge chemical state valence change of the hierarchical hollow Li4Ti5O12 urchin-like microspheres.

Real-time imaging of the filament growth process of a resistive memory has been achieved using a specially designed sample. By combining the in situ TEM technique and finite element method simulations, the correlation between the conductive filament growth and the electric field distribution and several other factors has been demonstrated.
