Composition of AGM battery and gel battery -Lithium - Ion Battery Equipment
The AGM battery uses pure sulfuric acid aqueous solution as the electrolyte, and its density is 1.291.3lg/cm3. Most of them exist in the glass fiber membrane, and at the same time, there is a part of electrolyte inside the electrode plate. In order to supply the oxygen released from the positive electrode to the channel of the negative electrode, it is necessary to keep 10% of the pores of the diaphragm not occupied by the electrolyte, that is, the lean solution design. The pole group is tightly assembled so that the plate can fully contact the electrolyte.
At the same time, in order to ensure sufficient battery life, the plate should be designed to be thicker, and the positive grid alloy should be Pb&rsquo- Q2w-Srr -- A1 quaternary alloy. The AGM type sealed battery has a small amount of electrolyte, a thicker plate and a lower utilization rate of active substances than the open type battery, so the discharge capacity of the battery is about 10% lower than that of the open type battery. Compared with today's colloidal sealed battery, its discharge capacity is smaller.(Lithium - Ion Battery Equipment)
Compared with the same specification battery, the price is higher, but it has the following advantages:
The cycle charging capacity is three times higher than that of lead-calcium battery, with longer service life.
It has higher capacitance stability throughout its service life.
Low temperature performance is more reliable.
Reduce accident risk and environmental pollution risk (due to 100% sealing of acid solution)
It is easy to maintain and reduce deep discharge.
Colloidal lead-acid battery adopts gel electrolyte, and there is no free liquid inside. Under the same volume, the electrolyte has large capacity, large heat capacity, and strong heat dissipation ability, which can prevent general batteries from being prone to thermal runaway; The electrolyte concentration is low, and the corrosion of the electrode plate is weak; The concentration is uniform and there is no electrolyte delamination.
It has the following characteristics:
1. High quality colloid is prepared by fumed silica, the electrolyte is evenly distributed, and there is no acid stratification.
2. The electrolyte is in a fixed state of gel, which is not flowing and has no leakage, so that all parts of the plate react evenly.
3. With tight assembly technology, it has excellent high rate discharge performance.
4. Excessive electrolyte, large thermal capacity of battery, strong heat dissipation capacity, and wide operating temperature range.
5. All high purity raw materials are used, and the self-discharge electrode of the battery is small.
6. Using gas recombination technology, the battery has high sealing reaction efficiency, no acid mist precipitation, safe and environmental protection, and no pollution.
7. Special design and highly reliable sealing technology are adopted to ensure that the battery is sealed, safe and reliable. Lead-acid battery has been the most widely used chemical power source in special civil fields since its appearance. Because it uses sulfuric acid electrolyte, acid will flow out during transportation, and acid mist will come out during charging, which will cause damage to the environment and equipment. People try to fix the electrolyte and seal the battery, so the lead-acid battery using colloidal electrolyte came into being.
The gel electrolyte used in the initial gel battery is made of water glass and then directly added to the dry battery. Although the purpose of fixing the electrolyte or reducing the precipitation of acid mist is achieved, the capacity of the battery is about 20% lower than that of the original battery using free electrolyte, so it is not accepted by people.
China also carried out the research and development of the initial gel battery in the 1950s, and basically stopped by the end of the 1960s. However, from the late 1970s to the 1980s, some people in the non-battery industry in China used the media to hype about the invention of solid electrolyte batteries, claiming to double the battery capacity and life. This kind of invention and creation of soap bubble, which cannot stand the test of facts, not only failed to improve the performance of battery, but also damaged the reputation of colloidal battery.
