What is Enhanced electrochemical performance of carbon–LiMn1−xFexPO4 nanocomposite cathode for lithium-ion batteries about?
a b s t r a c t 4 V-class olivine C-LiMn 1-x Fe x PO 4 (x = 0 and 0.15) are synthesized by ultrasonic pyrolysis followed by ball milling with AB carbon to evaluate the doping effect of iron. The C-LiMn 0.85 Fe 0.15 PO 4 shows excellent rate capability having discharge capacity of 150 mAh g -1 at 0.5C-rate and 121 mAh g -1 at 2C-rate. The capacity retention of the C-LiMn 0.85 Fe 0.15 PO 4 is 91% after 50 cycles at 55 • C whereas C-LiMnPO 4 is limited to 87%. The improved electrochemical performance of the C-LiMn 0.85 Fe 0.15 PO 4 electrode is attributed to the enhanced electrical conductivity caused by tighter binding on the carbon particles with the LiMn 0.85 Fe 0.15 PO 4 primary particles as well as by the surface coating of carbon on the primary particles.
