NOVELTY - Preparing battery slurry comprises mixing a conductive agent and a first solvent to obtain a mud-type conductive solid, mixing the mud-type conductive solid with an active material, adding a conductive glue and mixing to obtain the battery slurry. The conductive agent comprises conductive carbon black, single-wall carbon nano-tube, multi-wall carbon nano-tube, acetylene graphene or MXene. USE - The method is useful for preparing battery slurry. ADVANTAGE - The conductive agent in the battery paste is uniformly coated on the surface of the active material, so as to greatly improve the conductivity of the battery pole piece. The battery slurry has high stability, which can effectively avoid the problem that multiple conductive agents are easy to agglomerate in the slurry and low density coating is easy to generate scratch. The multiplying power performance and fast charging performance of battery are improved. The production efficiency of the electric core is improved, and shortens the preparation time of slurry. The charging and discharging-high rate system battery is provided with fast charging and fast discharging performance.
