Abstract
Improvement of the rate properties of orthorhombic LiVOPO4 by using a milling approach and acetylene black additives as electronic binder is investigated. The average particle size of orthorhombic LiVOPO4 was reduced from 12.0 μm to 6.1 μm by milling process by which the Li intercalation capacity into LiVOPO4 increased to 40 mAhg-1 at 0.4 mAcm-2 (C/5). At an optimized acetylene black amount of 15 wt.%, a better uniformity in particle size distribution and dispersion of the current distribution was obtained. Thus, enhancing the kinetic performance a fairly large reversible intercalation capacity of Li was achieved with values of 100 and 60 mAhg-1 at high rate conditions of C/5 (0.4 mAcm -2) and 1C (2 mAcm-2), respectively.
