AGM separators are made from ultra-fine glass fibers that form a highly porous, absorbent mat. This special structure allows the separator to fully absorb and retain the electrolyte, ensuring close contact between the positive and negative plates while preventing short circuits.
Unlike traditional polyethylene (PE) separators used in flooded batteries, AGM separators create a “dry” electrolyte environment, which is essential for sealed, valve-regulated lead-acid (VRLA) batteries.

Main Applications

AGM separators are widely used in various types of VRLA batteries, including:

• UPS (Uninterruptible Power Supply) systems

• Telecommunication and data center backup batteries

• Emergency lighting systems

• Electric scooters and mobility devices

• Automotive start-stop (EFB/AGM) batteries

• Solar energy storage systems

These batteries are commonly known for their maintenance-free design, as the AGM material enables efficient oxygen recombination, minimizing water loss and extending battery life.

Key Functions and Advantages

1. Electrolyte Absorption: The glass fibers hold the sulfuric acid within their pores, maintaining consistent ion flow between electrodes.

2. Enhanced Oxygen Recombination: Promotes internal gas recombination, preventing gas leakage and ensuring safety.

3. Low Internal Resistance: Enables higher discharge rates and better high-current performance.

4. Vibration Resistance: The tight compression of AGM layers helps protect plates from physical damage, especially in automotive use.

5. Maintenance-Free Operation: Eliminates the need to add water or perform frequent maintenance checks.

   
   

As global demand grows for clean energy and efficient power backup, AGM technology continues to evolve with improvements in fiber quality, porosity control, and acid absorption stability. Manufacturers are focusing on lightweight, high-strength AGM materials to meet the demands of electric vehicles, renewable energy storage, and other advanced applications.

In conclusion, AGM separators have transformed traditional lead-acid battery technology by combining safety, durability, and performance. Their continued innovation will play a key role in powering the next generation of energy solutions.
