Abstract
Nitrogen and sulfur co-doped graphene supported hollow ZnFe2O4 nanosphere composites have been successfully synthesized via a facile, two-step hydrothermal method. The obtained ZnFe2O4/NSG samples show interconnected hollow sphere nanostructure with a size of â¼250Â nm. The product demonstrated a high initial discharge capacity of 2478.6Â mAhgâ1 at a rate of 300Â mAgâ1. After 100 cycles, it delivered a high reversible capacity of 729.06Â mAhgâ1 and coulombic efficiency of 99.36%, while at high rate capability of 1800Â mAgâ1, the rate capacity stabilize at 650.1Â mAhgâ1. It is believed that the composite with good rate capability and stability can be a competitive anode for lithium-ion batteries.
