  "textContent": "This application relates to the electrochemical field, and in particular, to a positive electrode plate and related electrochemical energy storage apparatus and device. This application provides a positive electrode plate, including a positive current collector, a positive active material layer on at least one side of the positive current collector, and a safety layer between the positive active material layer and the positive current collector. The positive active material layer includes a positive active material. The safety layer includes a binding material, a conductive material, and an overcharge-sensitive material. The overcharge-sensitive material is a polymer that includes a monosaccharide structural unit and that includes at least one of a carbonate group and a phosphate group. An average diameter x of the conductive material and a weight-average molecular weight y of the overcharge-sensitive material satisfy Formula 1. The safety layer made of the overcharge-sensitive material according to this application is more reliable, so that the electrochemical energy storage apparatus is safer.",
