Lithium ferrite (Li0.5Fe2.5O4) nanoparticles as anodes for lithium ion batteries
Abstract
Li0.5Fe2.5O4 nanoparticles of about 80 nm were synthesized through a hydrothermal method, followed by a solid state reaction between LiOH·H2O and Fe2O3. The Li0.5Fe2.5O4 nanoparticles exhibit a remarkable high capacity (up to 1124 mA h g−1), a good cycle stability (650 mA h g−1 after 50 cycles) and excellent coulombic efficiency.
