Today, Caixin reporter learned from tayho advanced materials group that under the national standard testing conditions, the company's holding subsidiary Tayho Electric's aromatic polyamide lithium battery separator passed heavy object impact testing. During the test, after observing for 6 hours post heavy object impact, the aromatic polyamide lithium battery separator did not explode, did not catch fire, demonstrating a high level of safety, significantly enhancing the protective effect on the battery, and could be suitable for batteries with high safety requirements in the future. Xiaocai Note: The performance of aromatic polyamide coated separators in high temperature resistance, puncture resistance, oxidation resistance, and overall lifespan has been significantly improved, which can address the safety and mileage concerns of end-users of new energy autos. However, due to the high production difficulty and long market introduction period, initially only a few high-end models such as Tesla's overseas version of Model S are being used.
