Na-ion Product Directory

1. Ceramic-coated separators utilize proprietary coating technology, with uniform ceramic distribution, low moisture content, low shrinkage, stable coating, and excellent thickness consistency, making them a mainstream high-temperature-resistant, low-shrinkage coated product. 2. PVDF-coated separators offer excellent interfacial adhesion, enhancing overall battery strength and safety performance, with stable coating, uniform thickness, and consistent PVDF particle size and dispersion. 3. Ceramic & adhesive hybrid-coated separators integrate the advantages of ceramic and adhesive coatings, expanding new product functionalities. Leveraging fully proprietary technology, they open up new markets through two processes: composite coating and multi-layer lamination. 4. Oil-based aramid-coated separators exhibit outstanding heat resistance, low density, light weight, low moisture content, and significant voltage endurance advantages.

The nanofiber composite membrane product, which combines the advantages of both nanofibers and PP/PE, features the excellent wettability, electrolyte retention, high-temperature resistance, and anti-aging properties of nanofiber membranes, as well as the good tensile and puncture resistance of polyolefin membranes. This product integrates the benefits of lithium battery and supercapacitor separators, making it perfectly suitable for applications such as sodium-ion batteries, energy storage lithium batteries, high-rate batteries, and power vehicle batteries.

With a thickness of approximately 30μm, in the compression rebound test at 2MPa/1h/25°C, it can generate about 11% thickness compression space during compression and recover about 10% of the thickness after pressure release, effectively accommodating the thickness expansion requirements during the charge-discharge process of sodium-ion anode-free systems. The electrolyte retention and wetting performance are improved by over 40% compared to mass-produced wet-process separators.
