  "textContent": "A secondary battery includes a housing, and a cell assembly and an electrolyte that are disposed in the housing. The cell assembly includes a negative electrode plate, a separator, and a positive electrode plate that are sequentially stacked. The positive electrode plate includes a positive electrode current collector and a positive electrode active layer. The positive electrode active layer is disposed on at least one side of the positive electrode current collector. The positive electrode active layer includes a positive electrode active material and a dispersant. The dispersant is a polymer including an anchoring group and a siloxane segment, where the anchoring group includes a polar heteroatom-containing group and/or a derivative thereof.",
