What is the main difference between battery and gel battery

APR 22, 2019   Pageview:810

The difference is the way in which the electrolyte is fixed and penetrated inside the battery. The AGM is an ultra-fine glass fiber partition that absorbs the electrolyte and provides oxygen composite channels. The colloidal sio2 is used to fix the electrolyte in the colloidal battery.

The AGM type battery uses a pure aqueous sulfuric acid solution as an electrolyte with a density of 1.29-1 .3 lg/cm3. Most of them are found in glass fiber membranes, and at the same time, the inner plate absorbs a part of the electrolyte. In order to provide a channel to the negative electrode for the oxygen extracted from the positive electrode, it is necessary to keep 10 % of the pores in the diaphragm from being occupied by the electrolyte, that is, the lean design. The polar group adopts a tight assembly method so that the polar plate is fully exposed to the electrolyte. At the same time, in order to ensure that the battery has a sufficient life, the plate should be designed thicker, and the regular grid alloy adopts Pb '-q2w-Srr-A1 four-membered alloy. The AGM sealed lead battery has less electrolytic liquid, the thickness of the plate is thicker, and the utilization rate of the active substance is lower than that of the open battery, so the discharge capacity of the battery is about 10 % lower than that of the open battery. Compared with today's colloidal sealed batteries, its discharge capacity is smaller.

Compared with batteries of the same size, the price is higher, but it has the following advantages:

The recycling charging ability is three times higher than the lead calcium battery and has a longer service life.

It has higher capacitance stability throughout its life cycle.

Low-temperature performance is more reliable.

Reduce the risk of accidents and reduce the risk of environmental pollution(due to 100 % encapsulation of acid)

Maintenance is simple and reduces deep discharge.

The colloidal lead-acid battery adopts a gelatinous electrolyte, and there is no free liquid inside. Under the same volume, the electrolyte has a large capacity, a large thermal capacity, and a strong ability to heat dissipation, so as to avoid the phenomenon that the general battery is prone to heat runaway; The electrolyte concentration is low and the corrosion effect on the plate is weak. The concentration is uniform and there is no stratification of electrolytes.

Has the following characteristics:

1, gas phase silica prepared high-quality colloids, electrolyte distribution is uniform, there is no acid layer phenomenon.

2, the electrolyte is in a gel fixed state, no flow, no leakage, so that the polar plate parts react evenly.

3, adopts the tight assembly technology, has an excellent high rate discharge performance.

4, excessive electrolyte, battery heat capacity, strong thermal dissipation capacity, wide operating temperature range.

5, all use Gaochun raw materials, batteries self-discharge very small.

6, the use of gas recombination technology, the battery has a very high sealing reaction efficiency, no acid precipitation, safety, and environmental protection, no pollution.

Adopt special design and high reliability sealing technology to ensure that the battery is sealed and used safely and reliably.

The AGM sealed lead battery uses a pure aqueous sulfuric acid solution as an electrolyte with a density of 1.29-1 .3 LG/cm3. Most of the electrolytes are present in the glass fiber membrane, except for some of the electrolytes absorbed inside the polar plate. In order to provide a channel to the negative electrode for the oxygen extracted from the positive electrode, it is necessary to keep 10 % of the pores in the diaphragm from being occupied by the electrolyte, that is, lean liquid design. In order to make the electrode plate fully contact with the electrolyte, the polar group adopts a tight assembly method.

In addition, in order to ensure that the battery has a sufficient life, the plate should be designed thicker, and the regular grid alloy adopts Pb '-q2w-Srr-A1 four-membered alloy.

The electrolyte of the colloidal sealed lead battery is composed of silica Sol and sulfuric acid. The concentration of the sulfuric acid solution is lower than that of the AGM battery, usually 1.26 to 1.28 g/cm3. The electrolyte is 20 % more than the AGM battery, which is equivalent to a liquid-rich battery. This electrolyte exists in the colloidal state and is filled between the diaphragm and the positive and negative poles. The sulfuric acid electrolyte is surrounded by a gel and does not flow out of the battery.

Since this type of battery uses a liquid-rich non-tight assembly structure, the positive grid material can use low-antimony alloys or tubular battery positive plates. At the same time, in order to increase the battery capacity without reducing the battery life, the polar plate can be made thin. The internal space of the battery tank can also be expanded.
