Abstract
A positive electrode active material and a preparation method therefor, a positive electrode plate, a battery, and an electrical apparatus are disclosed. The positive electrode active material includes a transition metal oxide and a coating layer. The coating layer is coated on at least part of the surface of the transition metal oxide. The coating layer includes a silicon-containing polymer. The silicon-containing polymer is formed by polymerizing a silane monomer derivative containing a first group and polysiloxane containing a second group. The first group is reactive with the second group. The molecular weight of the silane monomer derivative is less than that of the polysiloxane.
