Abstract In this paper, we mainly discuss the effects of different dispersants on the stability of graphene dispersion in oily systems, and apply obtained conductive slurries with different dispersants on LiFePO₄(LFP) cathode to investigate their electrochemical performance. Test results show that the dispersion concentration and stability of graphene treated by dispersant BYK-2150 and KD1 in suspension are much better than ordinary dispersant polyvinylpyrrolidone (PVP). In addition, the batteries used BYK-2150 and KD1 conductive slurry exhibit a specific discharge capacity of 150.7 mAh/g and 156.1 mAh/g and the first discharge efficiency of 94.4% and 97.7% at 0.2C, respectively. After 50 cycles, their specific discharge capacity is 152.5 mAh/g and 159.7 mAh/g at 1C, respectively.
