The Battery Separator series, leveraging cutting-edge technology and precision manufacturing, serves as a critical enabler for the efficient and stable operation of batteries. The series comprises two main categories: PE separators and AGM separators, offering specialized solutions tailored to the specific requirements of different battery systems.
The development and production of PE separators are rooted in a deep understanding of material properties. The core raw material, high-density polyethylene (HDPE), possesses excellent physical and mechanical properties. During the melt-blown extrusion process, the raw material is melted at high temperatures and extruded through special nozzles, forming fibers that intertwine during cooling to create a preliminary porous framework; The stretching process precisely controls the direction and intensity of stretching to create a uniformly distributed microporous structure within the material. The diameter and density of these microporous structures are repeatedly optimized to provide sufficient channels for ion migration while effectively preventing direct contact between electrodes, thereby eliminating the risk of short circuits structurally. More importantly, the inherent chemical inertness of HDPE ensures its stability in the sulfuric acid electrolyte environment of lead-acid batteries. Whether subjected to long-term immersion or repeated charge-discharge cycles, it does not react chemically with the electrolyte or the active materials of the positive and negative electrodes, thereby maintaining the stability of the battery's internal chemical environment and significantly extending its cycle life.
AGM separators demonstrate the ultimate pursuit of ultra-fine material applications. They use high-purity silica-based glass fibers, which are drawn into ultra-fine fibers with diameters of only a few micrometers through a special process. During the forming process, these fibers are compressed into a felt-like structure through precise compression technology, with the gaps between the fibers forming a vast three-dimensional network of channels. To enhance compatibility with the electrolyte, the fiber surfaces undergo special hydroxylation treatment, significantly enhancing hydrophilicity. When the electrolyte is injected, the separator rapidly adsorbs and uniformly distributes the electrolyte. Additionally, the capillary action of the fiber network fixes the electrolyte into a gel state, preventing uneven distribution caused by electrolyte flow while providing a continuously stable medium environment for ion migration. This structure also endows the separator with excellent shock resistance. When the battery is subjected to external impacts or vibrations, the gel-state electrolyte is unlikely to leak, and the electrode structure remains stable, ensuring reliable operation of the battery in complex conditions such as automotive and energy storage applications.
Whether it is the chemical stability and efficient ion conductivity of PE separators or the superior electrolyte management and structural stability of AGM separators, these features highlight Zhongshan KenPo Plastic Co., Ltd.'s technical expertise in the battery separator field, providing a solid performance foundation for various battery products.
