Low-cost, one-step process for synthesis of carbon-coated LiFePO4 cathode

Lithium intercalation into amorphous FePO4 cathode in aqueous solutions

“…Subsequently, extensive work on this material has been carried out by a number of researchers [4][5][6][7][8] and LiFePO 4 is now recognised as the active cathode for a new generation of lithium batteries. This is due to its low cost, environmentally-friendly properties and good rechargeability.…”

Synthesis of LiFePO4/carbon composite from nano-FePO4 by a novel stearic acid assisted rheological phase method

“…Since FePO 4 is cheap and non-toxic, compared with the commonly used divalent iron starting materials such as FeC 2 O 4 or Fe(CH 3 COO) 2 , many research groups [21][22][23][24] have tried to use FePO 4 as starting material to prepare the LiFePO 4 /carbon composite with good electrochemical performance. These literatures [21][22][23][24] reported the synthesis of LiFePO 4 with good low-rate performance, but no one presented electrochemical performance data at rates * Corresponding author.…”

The Science of Electrode Materials for Lithium Batteries

“…Although the material is sufficiently conductive to be useful, it has many characteristics of an oxide insulator. Good success has been achieved by coating small particles of LiFePO 4 with a conductive carbon, and practical electrodes are made with this approach [85][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101]. Nevertheless, the rate capabilities are less than optimal, and the coating step requires careful process control.…”
