dc.description.abstract | We report a facile approach to synthesize hexagon-shaped nanoplates of various metal (oxy)hydroxides under aqueous solutions while avoiding complex processes. This synthetic method can be generally applied to fabricate various nanoplates, including not only single-metallic (oxy) hydroxides such as Co(OH)(2), MnO(OH), FeO(OH), and Mg(OH)(2) but also mixed-metal (oxy) hydroxides, where each metal component is homogeneously distributed and the atomic ratio of the metal species can be easily controlled by varying the precursor ratio. Carbon-coated metal oxide nanoplates, which are prepared by coating of polydopamine followed by heat treatment, are applied as anode materials for lithium-ion batteries (LIB). Core-shell nanoplates of CoO@C, MnO@C and Fe3O4@C exhibit excellent cycle stability with a high specific capacity of similar to 1000 mA h g(-1). In particular, the effect of carbon shell thickness on electrochemical performance is studied using CoO@C nanoplates with different carbon shell thicknesses. CoO@C with a 6.5 nm-thick carbon coating exhibits good cycling performance and maintains a high rechargeable capacity of 997 mA h g(-1) even after 100 cycles at a current density of 200 mA g(-1), while CoO@C with a 1.5 nm-thick carbon shell shows a significantly decreased capacity of 315 mA h g(-1) after the 100th cycle. | - |
