Organization of flakes into hollow, curved architectures (see figure) by means of an “aggregation‐then‐growth” process is described, providing in addition a fine example of a V 3+ nanostructure. The new‐phased VOOH hollow “dandelions” are shown to increase very effectively the capacity of lithium‐ion intercalation/deintercalation in batteries, especially at low temperatures.
