Interconnected LiCuVO4 networks with in situ Cu generation as high-performance lithium-ion battery anode

Abstract

Interconnected LiCuVO4 networks were synthesized through a facile surfactant-assisted approach. Detailed investigations on the lithium storage mechanism manifest that metallic Cu nanoparticles are generated in situ during the first discharge process and remain mostly intact in the following cycles, thereby enhancing conductivity of the electrode. The interconnected networks with submicron sized primary particles endow the LiCuVO4 with a large amount of active sites and thus high capacitive charge storage. Benefiting from a peculiar structure, the resultant interconnected LiCuVO4 networks deliver extraordinary rate performance (216 mA h g−1 up to 10 A g−1) and ultralong cycling stability (∼85% capacity retention after 5000 cycles at 5 A g−1). The exceptional rate performance and cycling stability show that the interconnected LiCuVO4 networks possess great potential for lithium-ion batteries.
