Novel CoNi binary metal oxide superstructures assembled with cross-stacked nanosheets (Co3O4/NiO/ NC) have been successfully prepared by two-step thermal annealing process with CoNi-based and cyano-bridged coordination polymer (CoNiCP). Ascribing to the super decussate structure and as obtained three-dimensional carbon conductive network, the obtained material exhibited excellent lithium-ion storage capacity including superior cycling stability and rate performance through facilitating the easy electron/ion transport. For example, CoNi binary metal oxide superstructures exhibit an excellent rate capacity of 493 mA h g(-1) at 5.0 A g(-1) and a long-lifetime cycling performance of 1390 mA h g(-1) after 100 cycles at 0.2 A g(-1). This strategy may pave a way for designing and preparing binary metal oxide superstructures materials with excellent electrochemical performance for lithium ion battery by using coordination polymers as the sacrificial template (C) 2020 Elsevier Inc.
