The invention provides an electrode slurry, a battery pole piece and a preparation method thereof. The battery pole piece includes a current collector and an electrode slurry film attached to the current collector; the electrode slurry film includes an active material, a conductive agent, Polymer binder with fluorophosphate. Compared with the prior art, the present invention adjusts the composition of the electrode slurry film, so that the prepared battery pole piece, especially the thick pole piece, has good loop performance and high rate charge and discharge performance, and the preparation method is simple. It is easy to implement and has low cost. It can be combined with existing production equipment and is suitable for industrial production applications. At the same time, the battery pole piece of the present invention contains a fluorophosphate, which can act as a flame retardant and improve the performance of lithium ion batteries. safety.nn n n M Z + [PO x F y ] Z (I) |
