  "textContent": "A positive electrode sheet containing a high-safety heat-sensitive coating and a lithium-ion battery containing the positive electrode sheet are provided. The heat-sensitive coating includes a first conductive agent, a first binder, heat-sensitive polymer microspheres and an auxiliary agent, and has a conductive property at normal temperature and also has advantages of increasing a contact area between an active material and a current collector, improving the conductivity, and effectively reducing the polarization of battery and the like; when the use temperature of the positive electrode sheet reaches 120° C. and above, the heat-sensitive polymer microspheres will melt to form a plurality of continuous electron blocking layers, current blocking occurs in the coating, an internal blocking forms inside the battery, thereby preventing the occurrence of further thermal runaway of lithium-ion battery.",
