In 2025, the global markets for new energy vehicles and energy storage systems are expected to continue growing, driving a significant year-on-year increase in lithium battery shipments. Consequently, shipments of the four major lithium battery materials are also set to rise sharply. The lithium battery materials industry has entered a new round of capacity expansion, with substantial scale-ups in production capacity. As power batteries are increasingly used on a large scale, safety remains a core technical challenge that urgently needs to be addressed. The growing demand for power batteries also pushes up the demand for separators, making the development of high-safety, high-performance separator technology an inevitable trend.

To meet high safety requirements, high-temperature-resistant and high-safety separators have become key areas of research in lithium-ion batteries. Among them, para-aramid/polyolefin composite separators, known for their excellent thermal shrinkage resistance and high puncture strength, have shown exceptional performance.

Para-aramid is a high-tech specialty material with excellent high-temperature resistance and stable chemical properties, making it highly sought after across various industries. However, due to its molecular rigidity and stress released during precipitation, it has been challenging to achieve mass production in separator coating applications.
