Abstract: A relatively simple galvanostatic method was used for the evaluation on the average chemical diffusion coefficient of lithium-ion in spinel LiVOPO4 prepared by rheological phase method.The diffusion coefficient of lithium-ion was estimated to be 4.78×10-11 cm2·s-1 and 3.27×10-11 cm2/s for charge and discharge,respectively.

Key words: diffusion coefficient, LiVOPO4, galvanostatic method
