A new method was developed to synthesize nanosheet-assembled TiO2–B microflowers for Li-ion batteries. Significantly higher electrochemical performance of these microflowers compared to other TiO2–B nanostructures was attributed to their hierarchical microstructure and exposed (1 ![[1 with combining macron]](http://www.rsc.org/images/entities/char_0031_0304.gif)
0) facets of the individual nanosheets.
