Thermal-resistant and flame-retardant membrane and preparation method thereof, and applications
ActiveCN110233224APrevent internal short circuitAvoid burning and explosionCell component detailsSecondary cells servicing/maintenancePhysical chemistryThermal stability
The present invention discloses a thermal-resistant and flame-retardant membrane and a preparation method thereof, and applications. According to the preparation method, the cost is controllable, theoperation of the preparation process is simple, and thus the preparation method is suitable for mass production. The prepared thermal-resistant and flame-retardant membrane has a double-layer composite structure with both thermal stability and flame retardancy, the membrane can prevent internal short circuit of a battery at a lower temperature, so that severe thermal runaway of the battery is prevented, and thus safety accidents, such as burning and explosion are prevented; the membrane can effectively prevent the battery from burning and exploding after the thermal runaway of the battery occurs under the conditions of overcharge, puncture and abuse; and the membrane has good applications in the chemical power supply system, especially in lithium ion batteries.
