NOVELTY - Preparing lithium ion battery slurry involves mixing active material, conductive agent and binder to obtain mixed material (A); adding mixed material (A) to solvent; controlling solid content of slurry to be 45-65%; stirring and mixing to obtain initial slurry (B'), and grinding initial slurry (B') using sand mill. USE - Method for preparing lithium ion battery slurry used as pole piece of lithium ion battery (all claimed). ADVANTAGE - The method enables to reducing active material preparation process and production cost, realizes quick preparing lithium ion battery slurry, improves production efficiency, avoids agglomeration of large particles and improves consistency of lithium ion battery.
