On May 10, 2023, Jinli Group successfully trial produced a 2 μ m diaphragm and achieved the level of large width sample delivery.

From the mass production of 5 μ m thick membranes in 2019 to 4 μ m membranes in 2020 and then to 3 μ m high-strength ultra-thin membranes in July 2022, after a gap of 10 months, the R&D team of Jinli Group has once again broken through innovation and developed an ultra-thin 2 μ m membrane, laying a solid foundation for the multi-directional development of the company's products, once again enhancing the brand's competitive advantage and continuing to maintain sustainable development.

The 2 μ m separator developed this time is mainly used for functional composite film base membranes or separators for semi-solid state batteries. The product features extremely thin thickness, low breathability, large pore size, and high porosity. It has a certain mechanical strength and plays a good role in safety barriers and support in composite membranes and semi-solid batteries.
Jinli Corporation will continue to strengthen technological innovation and independent research and development, adding hardcore power to become a world-class enterprise.
