NOVELTY - Preparing graphene composite carbon fiber felt comprises (i) adding binder to N, N- formamide, stirring and mixing uniformly, and then adding graphene and an organic solvent, stirring and mixing uniformly to obtain a mixed solution; (ii) locating the carbon felt, using a cutting device to slice the carbon felt, using a dust removal device to treat the dust, labeling and then immersing it in the mixture; (iii) taking out the soaked carbon felt, adding it in an oven to dry to obtain a graphene composite carbon felt; and (iv) stacking graphene composite carbon felt, recording the weight and adding into inventory. USE - The method is useful for preparing graphene composite carbon fiber felt. ADVANTAGE - The method improves adjustment of position of the cutter according to the cutting size.
