A facile one‐step template‐free method based on a novel inside‐out Ostwald ripening mechanism is developed for inexpensive mass preparation of hollow and hollow core/shell‐type SnO 2 nanostructures using potassium stannate as the precursor. As‐prepared SnO 2 hollow nanospheres (see figure) exhibit ultrahigh lithium storage capacity and improved cycle performance as high‐energy anode materials in lithium‐ion secondary batteries.
