Best of both worlds: A heterostructured material is synthesized that comprises a core of layered lithium‐rich material and an outer layer of nanospinel material. This spinel/layered heterostructured material maximizes the inherent advantages of the 3D Li + insertion/extraction framework of the spinel structure and the high Li + storage capacity of the layered structure. The material exhibits super‐high reversible capacities, outstanding rate capability and excellent cycling ability.
