What is Sealed Gel Battery?
VRLA GEL battery is a valve-regulated lead-acid battery (VRLA) + gel electrolyte battery technology battery. This is a lead-acid battery used for energy storage.
Sealed Gel Battery uses gel instead of liquid acid as an electrolyte. Gels are usually produced by uniformly dispersing fumed silica in dilute sulfuric acid. Fumed silica is a kind of silica powder with very good dispersibility, which can absorb more than 10 times its weight to produce a gel. Due to the thixotropy of the gel, the agglomerates connect themselves together to form a network, keep the liquid inside and become a gel structure after a certain gel time. There is no liquid inside the gel battery, and the electrolyte is in the form of a gel, which is solidly fixed between the positive and negative plates inside the battery.
Technical features of Sealed Gel Battery technology:
Use the gel as an electrolyte
The board thickness tolerance is not important, because the high compression of the board pack components is not necessary
More electrolyte has better contact with the electrode plates and active materials and container walls, which is beneficial to release internal heat and cool the battery temperature.
Using ultra-microporous partitions, you can:
a/ Reduce negative electrode depolarization and avoid sulfation of negative plate
b/ No liquid, significantly reducing thermal runaway
c/Help prevent short circuit release between positive plate and negative plate due to dendrite growth in the deepwater process
Better exhaust valve design reduces gas leakage rate and prolongs battery life.
Compared with flooded batteries, the advantages of Sealed Gel Battery are:
Maintenance-free, no need to add water
No liquid inside, safe operation
Can be installed horizontally (upside down is not recommended)
Long cycle life
Low self-discharge enables longer shelf life.
Since the electrolyte can be kept inside and stable, it has a long standby life
Performance remains high and stable until the end of the life cycle
Tolerate abuse and heat during operation, suitable for extreme weather
