Uniform SnO2 nanotubes with a mesoporous shell were successfully prepared by calcination of SnO2@polymeric nanotubes. The SnO2 nanotubes possess enhanced lithium storage performance compared with SnO2 hollow spheres and SnO2 nanoparticles owing to the unique structure of mesoporous shell, open ends and hollow interior.
