Özet:

 

We synthesized Nb-doped LiFePO4  /C nano composite cathode materials by  mechanochemical activation followed by a single step calcination. The starting  chemicals of Li2  CO3  , FeC2  O4  .2H2O, NH4  H2  .PO4   and C6  H8  O7   as lithium, iron,  phosphate, and carbon sources are mixed in a high energy ball mill  250 rpm, 5h   and calcined at 650 °C and 10 hours. The resultant materials are structurally  XRD,  SEM, TEM  and electrochemically characterized and high purity LiFePO4   with high  electrochemical performance is obtained. Voltage vs. specific capacity, discharge capacity  vs. cycle number in manufactured battery is presented. An initial specific discharge  capacity of 153 mAhg−1 and a specific discharge capacity of 128.4 mAhg−1 after the 8th  charge/discharge cycling at 1C is recorded.
