A synthesis of Li3V2(PO4)(3) being a potential cathode material for lithium ion batteries was attempted via a glass-ceramic processing. A glass with the composition of 37.5Li(2)O-25V(2)O(5)-37.5P(2)O(5) (mol%) was prepared by a melt-quenching method and precursor glass powders were crystallized with/without 10 wt% glucose in N-2 or 7%H-2/Ar atmosphere. It was found that heat treatments with glucose at 700 degrees C in 7%H-2/Ar can produce well-crystallized Li3V2(PO4)(3) in the short time of 30 min. The battery performance measurements revealed that the precursor glass shows the discharge capacity of 14 mAh g(-1) at the rate of 1 mu A cm(-2) and the glass-ceramics with Li3V2(PO4)(3) prepared with glucose at 700 degrees C in 7%H-2/Ar show the capacities of 117-126 mAh g(-1) (similar to 96% of the theoretical capacity) which are independent of heat treatment time. The present study proposes that the glass-ceramic processing is a fast synthesizing route for Li3V2(PO4)(3) crystals. (C) 2011 Elsevier B.V. All rights reserved.
