Confined-space synthesis of hierarchical SnO2 nanorods assembled by ultrasmall nanocrystals for energy storage

A genetically modified bacterial surface not only serves as a confined environment for controlling the monodispersity of particle size, but also provides a carbon source in situ. The carbon coated SnO2 composite exhibits good lithium storage properties as an anode electrode, which are due to the ultrasmall size of the particles, the carbon coating and mesoporous structure.
