In the present study, we have developed a simple and cost-effective approach for the synthesis of carbon coated LiFePO₄ wherein different carbon precursors were used to find out the suitable precursor for carbon coating. Initially, the appropriate amount of Li, Fe, and P precursors and carbon source (glucose/sucrose/fructose) were dissolved in ethanol solution followed by hydrothermal treatment at 180 °C to obtain carbon coated LiFePO₄. The structure and morphological analysis of carbon coated LiFePO₄ revealed the formation of thin and homogeneous carbon layer on crystalline single-phase LiFePO₄ particles with fructose used as carbon precursor.

Article Synopsis
  • The study synthesized carbon-coated lithium iron phosphate (LFP) using a flame spray pyrolysis unit and a novel dehydration assisted polymerization (DAP) method to enhance electronic conductivity.
  • Characterization confirmed a pure LFP structure with a uniform 6-8 nm thick graphitic carbon layer, resulting in improved electrochemical performance, with specific capacities of 167 mAh/g at 0.1C for DAP-coated LFP compared to 145 mAh/g for the traditional carbothermal process.
  • The DAP method also allowed for large-scale production (0.5 kg) of carbon-coated LFP, which exhibited impressive rate capability and cyclic stability, making it competitive with commercial electrode materials.
