PVDF (Polyvinylidene Fluoride) polymer and preparation method thereof, electrode slurry, electrode, battery and electric equipment

The invention relates to a PVDF (Polyvinylidene Fluoride) polymer and a preparation method thereof, electrode slurry, an electrode, a battery and electric equipment. The structural formula of the PVDF polymer comprises a first repetitive unit with a structure as shown in a formula (1), a second repetitive unit with a structure as shown in a formula (2-1) and/or a formula (2-2), and a third repetitive unit with a structure as shown in a formula (3). According to the polymer provided by the invention, self-crosslinking of part of monomers in the polymerization process can be avoided, meanwhile, the addition amount of the obtained polymer in the positive electrode slurry is lower, and the stripping force of a positive electrode plate can be improved while the viscosity of the positive electrode slurry is reduced. # imgabs 0 # formula (1) # imgabs 1 # formula (2-1) # imgabs 2 # formula (2-2) # imgabs 3 # formula (3).
