China is a major producer and exporter of lead-acid batteries in the world. Lead-acid batteries have a history of more than 200 years and are widely used as power sources. It has the advantages of easily available raw materials, low price and good reliability, and its current market share is about 95%. Lead-acid battery, as a stable power supply and the main power supply of DC, has a large demand and consumption, which is closely related to our social life. The design service life of lead-acid batteries is generally 10 year, but the actual service life is only about 1 year. Research has proved that if the battery is used and maintained improperly in the actual use process, such as frequent under-charging, untimely charging, long-term over-discharging, etc. Lead sulfate, a hard and coarse particle with poor conductivity, will be gradually formed on the electrode plate. This kind of lead sulfate is difficult to reduce when it is charged by conventional methods, and its charging acceptability is very poor, and a large amount of gas is precipitated. This phenomenon is called "irreversible sulfation" or "vulcanization" for short. Coarse lead sulfate blocked the pores of the electrode plate, making it difficult for electrolyte to penetrate, increasing internal resistance, resulting in the battery being unusable due to reduced capacity. At present, all kinds of lead-acid battery products, whether made in China or imported, usually have difficulties in charging and capacity reduction around 1 year, and will be scrapped prematurely, far from reaching the design life. In 2004 alone, China scrapped more than 654.38 billion lead-acid batteries every year, tens of thousands in small and medium-sized cities, hundreds of thousands or even millions in large and medium-sized cities, and more than 90% of them were scrapped because of sulfation. The premature scrapping of lead-acid batteries not only wastes energy seriously, but also pollutes the environment seriously. The recycling of waste batteries has become the focus of attention of governments at all levels, enterprises and institutions.
In the United States, Japan and some developed countries in the west, there are hundreds of thousands of employees engaged in the daily maintenance of lead-acid batteries and the recycling of used batteries, with annual benefits of hundreds of billions of dollars.
"Digital program-controlled repair technology of lead-acid battery particles" is a high-tech developed by Beijing Guo Da Lianchuang Technology Development Co., Ltd. by using the latest digital program-controlled technology of particles and international frontier theory, which can repair sulfide batteries as good as new. This technology organically combines physical and chemical desulfurization theory, which can effectively remove the sulfide in the battery plate, thus cleaning the battery plate at all times, maintaining and repairing the lead-acid battery, and keeping the plate in a brand-new state. The capacity output of the battery is stable, which completely changes the sulfation phenomenon of the battery and prolongs the service life of the battery to the maximum extent. The protection, detection and repair system of lead-acid battery adopts comprehensive maintenance means, which firstly accurately judges the capacity and aging degree of each battery group. Then carry out targeted balanced charging repair, adopt the latest patented particle wave repair technology leading in the world, control the scanning frequency, scanning frequency and particle wave change of particle wave through digital program, find out the * * vibration frequency of lead sulfate crystal, and send the particle wave to the electrode plate without damaging the electrode plate, thus generating * * vibration and transforming it into the most unstable lead sulfate molecule, and then control the repair through particle digital program, so as to gradually decompose and separate it from the battery electrode plate. It is transformed into a free ion state and enters the electrolyte, and returns to the initial state of the battery. The repair rate can reach more than 95%. It has the characteristics of high repair rate, wide application range, good repair effect, low cost and convenient use. At the same time, the system also has the functions of capacity detection, internal resistance detection, balanced charging and nondestructive repair. As long as the failed lead-acid batteries are produced by regular manufacturers according to the standard, whether they are imported or domestic, ordinary or maintenance-free, liquid-rich or liquid-poor, solid or colloidal, as long as they are scrapped due to vulcanization (except physical damage, such as electrode pieces falling off, internal open circuit and short circuit, etc.). ), this system can be used to repair them. Repairing a group of used batteries (bottles) only needs one degree of electricity, and the fees vary from 100-300 yuan, so the profit margin is huge. More details:
