Glass Fiber Battery Separator Felt refers to a porous, fibrous membrane material made of high-purity glass fiber (typically borosilicate glass or alkali-free glass) through processes such as non-woven needling or wet-laid forming. It serves as a core component in batteries (mainly lithium-ion batteries, sodium-ion batteries, and flow batteries), functioning to physically separate the positive and negative electrodes to prevent short circuits while allowing the free passage of electrolyte ions to ensure ion conduction. With excellent thermal stability, chemical inertness, and high porosity, it effectively enhances battery safety and cycle performance.
Demand for Glass Fiber Battery Separator Felt is primarily driven by the rapid development of the global new energy vehicle industry, the large-scale deployment of energy storage systems, and the increasing demand for high-safety, long-cycle batteries. Additionally, the continuous advancement of battery technology (such as high-voltage and high-energy-density batteries) further boosts the requirement for high-performance separators. Business opportunities lie in the R&D of ultra-thin, high-strength glass fiber separator felts to adapt to lightweight battery designs, the modification of surface properties to improve electrolyte wettability and compatibility, the expansion of applications in emerging battery types (e.g., solid-state batteries), and the optimization of production processes to reduce costs and improve large-scale production capacity.
