Abstract
3D porous nano/micro ZnFe2O4 has been prepared from the leach liquor of jarosite residue via a facile chemical coprecipitation method followed by sintering at 800 °C in air atmosphere. As anode material for lithium ion batteries, the prepared ZnFe2O4 exhibits high specific capacity, excellent rate capability, and good cycling stability, which can be due to the beneficial effects of primary nanocrystals of ZnFe2O4, the unique 3D porous nano/micro structure, and the associated pseudo-capacitive behavior during discharge/charge processes.
