Abstract

Hierarchical Sb was successfully fabricated via a very simple and cost-effective electrochemical deposition method. Morphological and structural characterizations show that the as-prepared Sb has a uniform fern leaf-like structure which is composed of well-crystallized Sb nanoparticles. The formation mechanism of the fern leaf-like Sb was also investigated. The hierarchical Sb exhibits desirable properties for sodium storage, such as high electrical conductivity and large surface area. When used as an additive-free anode for Na-ion batteries, the as-obtained fern leaf-like Sb reveals excellent cycling stability and rate capability. It can afford a high reversible capacity of 589 mA h g−1 over 150 cycles at 0.5 A g−1 and retain a capacity of 498 mA h g−1 at a high rate of 10 A g−1. Furthermore, a full cell constructed using P2-Na2/3Ni1/3Mn2/3O2//fern leaf-like Sb also displays remarkably stable and robust Na-storage performance, which includes a high capacity retention of 70% after 100 cycles at 0.5 A g−1 and a large capacity of 370 mA h g−1 at 10 A g−1. The excellent electrochemical performance of fern leaf-like Sb can be attributed to its morphological and structural features that ensure fast ion and electron transport and a stable electrode structure.
