| Description |
Nanoporous LiFePO4/C composite cathodes have been synthesized by a novel one-pot, glycine-assisted
combustion (GAC) method in presence of 2 wt.% Super P carbon in both Ar and 90% Ar–10% H2 atmospheres
at 750 ◦C for a short time of 6 h. While the Ar atmosphere offers phase pure samples, the
Ar–H2 atmosphere leads to the formation of impurity phases as indicated by X-ray diffraction data. The
combustion-initiated expulsion of gases aids the formation of a nanoporous LiFePO4/C composite structure
as evident from electron microscopic analysis, which could allow easy penetration of the electrolyte
and realization of an electronic–ionic 3D network. The nanoporous LiFePO4/C sample synthesized in Ar
atmosphere exhibits a high discharge capacity of 160mAhg−1 with 3% capacity fade in 50 cycles and
high rate capability. With a short reaction time, the GAC method offers an energy efficient approach to
synthesize high performance olivine LiFePO4/C composite cathodes.
