摘要：
Hierarchical Bi2MoO6 nanosheet arrays (BNAs) growing on three-dimensional (3D) Ni foam are synthesized by one-step template-free route. The obtained BNAs are used as binder-free integrated electrode for Li-ion batteries (LIBs) directly. The electrode exhibits a super high reversible discharge capacity of 2311.7 mu Ah.cm(-2) (1741.4 mAh g(-1)), and an excellent cycle stability. The outstanding electrochemical properties are reasonable from the self-supported integrated electrode in which the electrolyte is easy to infiltrate active materials, electrons and ions are readily transported along the 3D conductive substrate and the stable electrode structure.
