　　Prussian blue and its analogues have been attractive in modern electrochemical reversible energy storage systems.However,the study of Prussian blue analogues as anode materials for lithium-ion batteries so far is very limited.Herein,Prussian blue analogue(PBA)and carbon nano tube compound anode,K0.46Fe2.08(CN)6·3H2O@CNT(PBA@CNT),were synthesized via a low-cost and simple solution precipitation method.The compound exhibited excellent cycling stability with no capacity loss even after 400 cycles at a specific capacity of around 400 mAh g-1.Furthermore,superior rate capability of 405 mAh g-1 and 208 mAh g-1 were obtained when the discharge current density at 500 and 2500 mA g-1 respectively due to the nano particle sizes,open-framework structure of the PBA,the dispersion,and the high conductivity of carbon nano tubes.In brief,the PBA@CNT compound displays excellent electrochemical performance and is highly promising for further study.
