Abstract

Herein we report on using Egyptian blue as an anode material for Li-ion batteries. A 1^stcycle lithiation capacity of 594 mA h g⁻¹and reversible capacity of 210 mA h g⁻¹at 20 mA g⁻¹, and at 500 mA g⁻¹a reversible capacity of 120 mA h g⁻¹(stable over 1000 cycles) were achieved with coulombic efficiency more than 99.5%. Using X-ray diffraction, and FTIR and X-ray absorption spectroscopies we found that the material goes through a conversion reaction during the 1^stcycle that results in the formation of amorphous mixed oxides with copper nanoclusters.
