Abstract
The application relates to a positive electrode sheet, a battery cell and a positive electrode sheet preparation process, and relates to the technical field of battery preparation. The positive electrode sheet comprises a current collector and an active layer. The active layer comprises a first active layer and a second active layer, the first active layer is arranged on the current collector, and the second active layer is arranged on the side, away from the current collector, of the first active layer. One of the first active layer and the second active layer is arranged as lithium manganese iron phosphate, and the other is arranged as a mixture of lithium manganese iron phosphate, a ternary positive electrode material and a low-voltage lithium-rich manganese-based positive electrode material. The positive electrode sheet provided by the application can use lithium manganese iron phosphate as a positive electrode material while taking into account the energy density, cycle life and performance rate of the electrode sheet, so as to meet different application requirements.
