Recent developments in nanotechnology and materials science offer potential solutions to the questions of how to improve performance and safety, as well as enhance the reliability of lithium-ion batteries (LIBs): the dominant power source for portable electronic devices. A wide range of nanostructured materials have been shown to exhibit enhanced electrochemical properties as promising electrode materials for high-performance LIBs. In this review article, we will discuss two metal oxides with sheet-like nanostructures: tin dioxide (SnO2) and titanium dioxide (TiO2). For SnO2 nanosheets, we discuss different systems for synthesizing such nanostructures and their application as the anode material for LIBs. In view of many recent review articles summarizing the various strategies for the preparation of TiO2 nanosheets, here we will stress the effect of this unique structure with exposed (001) facets on their lithium storage properties. By looking at these metal oxide nanosheets, we aim to provide some rational understanding of this unique category of nanomaterials and their electrochemical properties associated with their novel structures.
