| description | The invention provides a preparation method of oily conductive agent slurry and an electrode plate, and an assembly method of a battery. The preparation method of the oily conductive agent slurry comprises the following steps of mixing NMP and dispersing agent, and uniformly stirring to obtain a first mixture, shearing, grinding and stripping the heat-treated graphene, and mixing the graphene witha parts of the first mixture to obtain second mixture, mixing the carbon nanotubes subjected to heat treatment with a parts of the first mixture, and performing turbine dispersion treatment to obtaina third mixture, carrying out mixing treatment and vortex dispersion treatment on the second mixture and the third mixture to obtain a fourth mixture, and carrying out demagnetization and defoaming treatment on the fourth mixture to obtain the oily conductive agent slurry. The method is advantaged in that the dosage proportion of the oily conductive agent in the battery can be reduced, and conductivity of the electrode ma |
