Fabrication and Electrochemical Performance of LiFePO4/C as Cathode Material for Lithium Ion Battery

The research for cheap and abundant LiFeP04/C as cathode material of lithium-ion battery became a trending topic in this century. LiFePO
4
/C particles were commonly used due to its environmental acceptability. This research was aimed to compare methods for preparing LiFePO
4
/C particles using solid state and flame assisted spray pyrolysis method. The variable of studied at variation molar ratio
$\mathrm{Li: Fe: P}$
of
$1: 1:1\ 1.1:1:1:\ 1.2:1:1$
; and
$1.3: 1: 1$
. The crystalline structure was characterized by X-Ray Diffraction (XRD). The morphology was characterized using SEM test. The electrochemical performance was characterized using battery analyzer. Based on data, still exhibits some impurities. The particle still in micron-sized. The highest initial discharge capacity at molar ratio
$\mathrm{Li: Fe: P}$
of
$1.1:1:1$
is 46.1 mAh g
⁻¹
at 1/20 C.
