Product Advantages
From consumer electronics and electric vehicles to large-scale energy storage systems and power tools, the unique properties of PVDF coated separator make it an indispensable component in modern battery technology. The PVDF coating layer can interact with the electrolyte in a lithium-ion battery to form a stable gelled conductive polymer, significantly enhancing the battery's performance. Our PVDF coated separator offers the following advantages over standard separator:
- It increases the liquid absorption and liquid retention of the electrolyte, greatly improving the safety of the battery.
- It reduces the expansion rate and leakage rate of the battery.
- It improves the cycling performance of the battery.
- The PVDF coating can bond the separator to the pole piece, increasing the hardness of the pole piece and making the battery stronger and easier to process and transport.
