Egyptian blue: from pigment to battery electrodes
Herein we report on using Egyptian blue as an anode material for Li-ion batteries. A 1(st) cycle lithiation capacity of 594 mA h g(−1) and reversible capacity of 210 mA h g(−1) at 20 mA g(−1), and at 500 mA g(−1) a reversible capacity of 120 mA h g(−1) (stable over 1000 cycles) were achieved with co...

Sumario: | Herein we report on using Egyptian blue as an anode material for Li-ion batteries. A 1(st) cycle lithiation capacity of 594 mA h g(−1) and reversible capacity of 210 mA h g(−1) at 20 mA g(−1), and at 500 mA g(−1) a 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(st) cycle that results in the formation of amorphous mixed oxides with copper nanoclusters. |
