บทคัดย่อ/คำอธิบาย :

Carbon-coated LiFeBO3 has been successfully synthesized by solid state reaction method at 750 °C under Ar atmosphere. Adipic acid was chosen for the source material for carbon during synthesis process. X-ray diffraction pattern confirms the formation of phase with monoclinic structure. Scanning electron microscopic study vindicates the particulate nature of the synthesized LiFeBO3 with weak agglomeration. Electrochemical impedance spectroscopy parallels the enhanced conducting properties of carbon-coated LiFeBO3 rather pristine LiFeBO3. The Li/carbon-coated LiFeBO3 and LiFeBO3 cells presented the initial discharge capacities 93 and 47 mAh/g, respectively. After few cycles, the carbon-coated LiFeBO3 exhibited stable discharge behavior (~53 mAh/g), whereas bare LiFeBO3 is concerned because poor electrochemical performance has resulted.
