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 V3+ 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.
