Abstract
Abstract Iron antimonide, FeSb 2 , has been prepared by levitation melting. The electrochemical cycling behaviors of FeSb 2 were evaluated using lithium-ion model cell Li/LiPF 6 (EC+DMC)/FeSb 2 . It was found that the reversible capacity of FeSb 2 in the first cycle reached 507 mA h g −1 , and a reversible capacity of about 282 mA h g −1 was still maintained after 15 cycles. In our present work, we also found that the FeSb 2 /mesocarbon microbeads (MCMB) composite material possessed higher initial reversible capacity and better cycle life than pure FeSb 2 , which made it suitable for use as anode material in rechargeable lithium-ion batteries.
