  "textContent": "This application relates to the technology field of batteries, and provides a positive electrode sheet and a battery, including a positive electrode current collector and a positive electrode active material layer disposed on a surface of the positive electrode current collector. The positive electrode active material layer includes a positive electrode active material, and includes a concave-convex area including a plurality of concave portions and convex portions disposed corresponding to the concave portions. In a nitrogen environment, the positive electrode active material layer has a weight loss rate ρ in a temperature range from 35° C. to 450° C., and the ρ satisfies: 1.1%-6%.",
