摘要：

Hierarchical porous ZnCo2O4 microspheres were fabricated at different temperatures by using Prussian Blue Analogue (PBA) Zn-3[Co(CN)(6)](2)center dot xH(2)O as precursor. ZnCo2O4 obtained at 550 degrees C exhibits the best electrochemical performance, with 1st discharge capacity of 1737.1 mAh g(-1) at 100 mA g(-1), and remains at 1051.6 mAh g(-1) after 100 cycles. The excellent electrochemical performances attribute to the porous structure, which facilitates the diffusion of Li+ and the migration of electrons. (C) 2015 Elsevier B.V. All rights reserved.
