Abstract
A facile soft-template self-assembly strategy is reported to synthesize monodispersed ZrO2 hollow nanospheres of size 28 ± 2 nm as a candidate for anode material in lithium-ion batteries (LIBs). Triblock copolymeric micelles of poly (styrene-b-2-vinyl methyl pyridinium iodide-b-ethylene oxide) (PS-PVMP-PEO) with core–shell-corona architecture serve as an efficient scaffold for the synthesis of ZrO2 hollow nanospheres using Zr(IV) butoxide as metal source. The ZrO2 hollow nanostructured electrode delivers a stable capacity of 97 mAh.g−1 after 100 repeated charge/discharge cycles at a high current density of 1C rate, which is four-fold higher than that observed for dense ZrO2.
