摘要:
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. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
