Latest Industrial Lithium Battery Industry Research -Lithium - Ion Battery Equipment
In the era of low-carbon economy, my country has achieved rapid development in new energy, energy conservation and emission reduction. Due to its high energy and environmental protection advantages, industrial lithium-ion batteries have begun to replace traditional lead-acid batteries, nickel-metal hydride batteries and nickel-cadmium batteries and become an important energy storage element in the 21st century.
Scope of use
Industrial lithium-ion batteries are widely used in hydraulic, thermal, wind, solar power plants and other energy storage power systems, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, special equipment, special aerospace and other fields. Let's briefly talk about electric vehicles. As far as my country's current situation is concerned, the continuous increase in the number of cars not only brings great trouble to traffic, but also causes serious environmental pollution due to the exhaust gas and noise emitted by cars. Especially in large cities, the impact is obvious. Li-ion batteries have been used in the field of electric vehicles due to their advantages of no pollution, less pollution, light weight and small size. It can also be seen in daily life, like our mobile phones, cameras, electronic watches, and even children's toys are used as energy storage power sources.(Lithium - Ion Battery Equipment)
The summary process is as follows:
When pulping, the positive and negative active substances in the powder are separated by special solvent and adhesive, and after high-speed stirring, there are positive and negative substances in pulping.
Coating film The slurry is uniformly coated on the surface of the metal foil, and after drying, it is divided into positive and negative electrode sheets.
Install from top to bottom in the order of positive-gap-negative-gap, enter the battery core from the winding, and then enter the product battery through the process of injecting electrolyte and sealing, that is, the end of the battery installation process.
The product battery is tested by special battery charging and discharging equipment, each battery is tested, and qualified product batteries are screened and delivered for use.
How many kinds of batteries are there? Batteries can be divided into: primary batteries (primary batteries); secondary batteries (rechargeable batteries) lead-acid batteries. Secondary batteries can be divided into: nickel-cadmium batteries, nickel hydroxide batteries, lithium-ion batteries, alkaline zinc-manganese batteries. Lithium-ion batteries are secondary batteries. Lithium-ion battery packs have the advantages of high storage density, light weight, long service life, small size, and low self-discharge. Lithium-ion batteries are two-thirds the size of lead-acid batteries and one-third the size of lead-acid batteries. Of course, with the continuous development of cathode technology, we can also use LiMn2O4 and LiFePO4 as cathodes, which is expected to greatly reduce the cost of lithium-ion batteries.
The market share of Chinese companies expanded. After more than ten years of development, the global lithium-ion battery industry has basically formed the national model of China, Japan and South Korea. my country, South Korea and Japan have their own characteristics in the lithium-ion battery market competition. For my country's power lithium battery companies, under the protection of policies, they are becoming larger and stronger. It is understood that among the top 20 global lithium-ion battery sales in 2016, Chinese companies occupied 15 seats. Among the only 6 companies with annual sales of 10 billion yuan, there are 3 companies in my country, 2 companies in South Korea, and 1 company in Japan.
