A High Performance K0.46Fe2.08(CN)6·3H2O@CNT as an Anode Material for Lithium ion Battery
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.
