2V lead-acid batteries were first made by Gasten Plante in 1860 and have a history of more than 140 years. For more than one hundred years, with the development of science and technology, the process, structure, production mechanization, and automation of 2V lead-acid batteries have been continuously improved, and their performance has been continuously improved.
What types of lead-acid batteries can be divided into?
What factors affect the life of lead-acid batteries?
Where can lead-acid batteries be used?
1 . Classified by purpose
Mainly divided into several aspects such as starting use, fixed use, power use, and so on. Among them, starting batteries are mainly used for starting and lighting various automobiles, locomotives, and ships. It is required to be able to discharge at a large current, be able to start at a low temperature, the internal resistance of the battery should be small, and the positive and negative plates should be thin. Stationary 50Ah 2V lead-acid batteries are mainly used as backup power sources for various large-scale equipment systems, with thicker plates, thinner electrolytes, and long service life. Power batteries mainly provide power for various power systems, and both long-term and short-term performance requirements are relatively good.
2 . Classified by plate structure
Mainly divided into paste type, tube type, and forming type. The lead oxide is adjusted into a lead paste with a sulfuric acid solution and then coated on the grid cast with lead alloy. After drying and forming, it is called a paste-coated pole plate. The frame is made of lead alloy, and the frame is sheathed with a woven fiber tube, and the active material is filled in the tube. This kind of pole plate is called a tubular pole plate. The plate is made of pure lead, which is called formation type.
3 . Classified by electrolyte and charging maintenance
Mainly divided into dry discharge batteries, dry charged batteries, wet charged batteries, maintenance-free, low-maintenance batteries, valve-controlled sealed batteries, etc.
The cycle life of a 2V lead-acid battery refers to the number of repeated charging and discharging of the battery, which is a cycle from full to full discharge. The cycle life of 2V lead-acid batteries is also closely related to the charging and discharging conditions. Generally, the larger the charging current (the faster the charging speed), the shorter the cycle life; charging according to the standard current, shallow charge, and shallow discharge can effectively extend the cycle life of the battery. With the deepening of use, the decay of battery capacity is inevitable. When the capacity decays to a certain value, the end of life can be judged.
50Ah 2V Lead-acid batteries can cope with high-current discharge in a short time, and the depth of discharge is not deep at this time. When discharging with a small current, even if the depth of discharge is slightly deeper, it has little effect on the life of the battery. The battery is most afraid of continuous high-current deep discharge. The factors that affect the life of 2V lead-acid batteries include the internal factors of the plate, such as the composition of the active material, crystal form, porosity, plate size, grid material and structure, etc.; it also depends on a series of external factors, such as discharge current density, Electrolyte concentration, and temperature, depth of discharge, maintenance status and storage time, etc.
Due to its excellent price-performance ratio, until today the output and application of 50Ah 2V lead-acid batteries are still at the top of various chemical power sources." Its applications mainly include power, starting, emergency, and working power, and the objects of use include vehicles, ships, airplanes, and telecommunications. Systems, computers, instruments, and other equipment and facilities, especially in automotive batteries and industrial batteries,2V lead-acid batteries account for more than 90% of the market share and have an absolute advantage.
