  "textContent": "Disclosed are a negative electrode plate and use thereof. For the negative electrode plate provided in the present disclosure, a negative electrode active layer is coated with a safety function layer containing metal and ceramic, which effectively improve an electrode potential of a negative electrode and a nucleation energy barrier of metal lithium of a lithium-ion battery in a charging process at a low temperature and a high rate, thereby avoiding occurrence of a lithium precipitation phenomenon at the negative electrode. Because of good heat insulation performance of the ceramic, occurrence of a thermal runaway phenomenon in a nail penetration test may be effectively avoided, and safety performance of the battery may be improved. When the negative electrode plate is applied to the lithium-ion battery, the obtained lithium-ion battery has advantages of good cycling performance and high security.",
