Lead-acid batteries, as mature and reliable energy storage technologies, continue to play a significant role in the new energy sector. Among them, AGM separator batteries and gel batteries have dominated the niche market due to their unique structural designs. The AGM (Absorbent Glass Mat) separator battery uses superfine glass fiber cotton as the electrolyte carrier and realizes the solidification and storage of the electrolyte through the adsorption structure. This design ensures that there is no free electrolyte inside the battery, providing excellent leak-proof performance. Meanwhile, the fine pore structure formed by ultra-fine glass fibers significantly enhances the oxygen recombination efficiency, greatly reduces water loss, and achieves maintenance-free characteristics. Its plates are made through a tight assembly process, which results in lower internal resistance and outstanding high-current discharge performance. It performs exceptionally well in scenarios such as automotive start-stop systems and emergency power supplies. The wide operating temperature range from -40 ° C to 60 ° C further expands its application boundaries.

Colloid batteries take silica sol gel electrolyte as the technical core. By uniformly mixing dilute sulfuric acid with silica powder, a thixotropic gel with a three-dimensional network structure is formed. This semi-solid electrolyte not only retains the ionic conductivity of the liquid electrolyte but also inhibits the shedding of active substances on the plates through a colloidal framework, thereby increasing the cycle life by more than 30%. The thermal stability of colloid batteries is particularly outstanding. In high-temperature environments, the colloid structure can effectively buffer the problem of electrolyte stratification. Combined with a unique gas recombination system, the self-discharge rate is 20% lower than that of AGM batteries. Its outstanding deep cycle performance makes it an ideal choice for long-term float charging applications such as solar energy storage and communication base stations. In some energy storage projects in certain regions, it has achieved an actual service life of over 12 years.

Both technical approaches have their own advantages: AGM batteries are known for their high power density and low-temperature starting performance, while gel batteries excel in cycle life and high-temperature stability. With the continuous iteration of lead-acid battery technology, the fiber diameter of AGM separators has exceeded the 1-micron level, and the thixotropic performance regulation accuracy of colloid electrolytes has reached 0.1Pa·s, driving lead-acid batteries to regain new vitality in emerging fields such as new energy storage and peak shaving in smart grids. When making a choice, it is necessary to comprehensively consider the power demand, temperature conditions and cycle depth requirements of the specific scenario. The two together constitute an indispensable and important branch in the lead-acid battery technology system.
