Abstract:

Triclinic α-LiVOPO4 that was prepared at 500°C by citric acid assisted sol-gel technique revealed uniform carbon coating and inter-agglomerate voids/pore-like morphologies from XRD, TG/DTA, SEM, FE-TEM and BET studies. When tested for Li-ion insertion properties, α-LiVOPO4/C cathode delivered an initial discharge capacity of 163 mAh/g (98% of theoretical value) at C/20 rate with impressive capacity retentions until 50 cycles attributed to the combined contributions of surface coating and porous structure that serve as facile electrical conduits for ion/electron transport.
