Due to the lower cost and larger abundance of Na, Na-ion batteries have been a potential alternative to Li-ion batteries for energy storage devices. The development of electrode materials or structures with good electrochemical performance is currently key task in Na-ion batteries research. In this work, we presented a highly ordered 3D nanostructure array with large-scale high ordering, well vertical alignment, and large interval spacing, fabricated by a facile and cost-effective nanoimprinted AAO templating technique, might be successfully used as an electrode and showed an excellent electrochemical performance. This arrays conceptual design is universal to most of electrode materials. In return for this electrode design, high ion accessibility, fast electron transport, and strong electrode integrity are presented. Used as additive- and binder-free anode for Na-ion batteries, the electrochemical performances are greatly enhanced. This work may open up more applications of such highly ordered 3D nanostructure arrays in energy storage systems.
