Descripción
Sumario:A NiFe(2)O(4)/expanded graphite (NiFe(2)O(4)/EG) nanocomposite was prepared via a simple and inexpensive synthesis method. Its lithium storage properties were studied with the goal of applying it as an anode in a lithium-ion battery. The obtained nanocomposite exhibited a good cycle performance, with a capacity of 601 mAh g(−1) at a current of 1 A g(−1) after 800 cycles. This good performance may be attributed to the enhanced electrical conductivity and layered structure of the EG. Its high mechanical strength could postpone the disintegration of the nanocomposite structure, efficiently accommodate volume changes in the NiFe(2)O(4)-based anodes, and alleviate aggregation of NiFe(2)O(4) nanoparticles.
