POSITIVE ELECTRODE PLATE, BATTERY, AND ELECTRIC APPARATUS

原文（中国語）

A positive electrode plate, a battery, and an electric apparatus. The positive electrode plate includes a current collector and an active material layer disposed on at least one side surface of the current collector. In a mixed active material layer, a positive electrode active material includes a first positive electrode active material and a second positive electrode active material, an average particle size Rof the second positive electrode active material is greater than an average particle size Rof the first positive electrode active material, R/R≥2, and the first positive electrode active material or the second positive electrode active material accounts for 55% to 95% of a total mass of the positive electrode active material in the mixed active material layer.
