Zhengzhou lithium battery assembly franchise is not true. Zhengzhou Oushibo Lithium Battery has been officially registered with the industrial and commercial industry and has qualified trade qualifications. Therefore, the Zhengzhou Oushibo Lithium Battery scam is fake. This type of franchise fraud is common because there is no franchise for lithium battery equipment. Lithium battery is a battery containing lithium (including lithium metal, lithium ion, lithium polymer) in the electrochemical system. Lithium battery is mainly divided into two categories: lithium metal battery and lithium ion battery. Among them, the lithium-ion battery is a secondary battery. (rechargeable batteries) rely primarily on the movement of lithium ions between positive and negative electrodes to function. During charging, the Li is disintercalatede the positive electrode and integrated into the negative electrode through the electrolyte. state ; during discharge, the opposite is true. This first charging and discharging process is the lithium ion integration and deintercalation process, which is vividly called "rocking chair battery".
Are Dongguan lithium batteries all scammers?
The biggest problem with using smartphones is power consumption. Power banks have therefore become an important supporting role. However, there are many online purchases and auctions. Trap, be careful not to buy a dodgy battery! ? ?Battery types are divided into several types: ?Ni-MH battery or nickel-cadmium battery: ?It has a memory effect, will explode if used incorrectly and has a short lifespan. battery life. it is no longer a consumer battery. Li-Ion Battery: This battery ist mainly used in mobile power supplies. It has no memory effect. However, if the charging time is too long and it overheats, the integrated circuit on the machine board that automatically cuts off the power is stolen. , “Spontaneous combustion” or “explosion” may still occur. Li-Polymer battery: The latest technology. Today's smartphone batteries use lithium polymer batteries. There is no memory effect and charging can be interrupted at any time. The battery size can be ultra-thin and the battery will never explode. ? Do these two power banks look familiar? That's right, it's a mainland Chinese public model. You can see it in group purchases, online purchases and auctions. “Every manufacturer went to the mainland factory to buy goods, and the boasting became more and more outrageous. The capeLithium-ion battery capacity has soared from 12,000 to 18,000. Now it boasts of 20,000 mAh. 200,000mAh. The top one is equipped with four 18650 lithium batteries and the bottom one is equipped with six 18650 lithium batteries. Since the size of this lithium ion battery is 18.25 x 65mm, the factory number is usually XXX18650-XX. The quality classification of lithium-ion batteries from top to bottom is:Japanese batteries such as Sanyo, Panasonic. . and other batteries: The capacity of a single cell is at least 3100 mAh, and the latest manufacturing process is about to launch a single cell of 4000 mAh. The quality is very good and we promise one year warranty, but. No one in online shopping or auctions will adopt it because the price is too high. ? ?Korean products like Samsung: Samsung Battery capacity numbers produced by nOur own factory are: ICR18650-30A, ICR18650-28A, ICR18650-26F, ICR18650-26D, ICR18650-24F, ICR18650-24E, ICR18650-22F. ?p.s: 30A represents a capacity of 3000mAh, and 22F represents a capacity of 2200mAh. Korean Satellite Factory A best quality factory in mainland China. It has been certified by Samsung in mainland China and authorized the local factory to produce 18650 batteries. ? Quality is divided into four levels: A01, A02, A03, A04. The first level is reserved by Samsung for its own use, and A02~A04 is sold to customers. Most of the mobile power supplies on the market are called Samsung. batteries, and the battery capacity is A02~A04. The numbers are: ICR18650-20, ICR18650-22, ICR18650-24, ICR18650-26 (Note: 20 represents 2000 mAh capacity, 26 represents 2600 mAh capacity). ? Mainland China factory: ? The battery number is also mixedat 18650. Most capacities are only between 1600 and 1800 mAh, but there is 3000 mAh. “At present, this type of battery is the most popular in group purchases and online purchases. Exposing the mask of the large capacity of lithium-ion batteries? In group purchases, online purchases and auctions, there are many batteries claiming to have a capacity of 18,000 mAh but only selling for 699. Their capacity is calculated like this. : ?< 3000 x 4 = 12000mAh > It's the one above The battery capacity is not 3000mAh at all. ? Judging by the serial number, the ICR18650-30A is produced by Samsung's own factory. It is kept in Korea for its own use and will not be sold to customers! What about capacity? 3000 x 4 = 12000? Maximum is 2200 x 4 = 8800mAh, maybe the capacity is even lower! [3000? ?Is there a more sinister approach? ? I have theregret to tell you that it has already entered the market! ?Because the size of 18650 batteries is the same. As long as they are remanufactured after recycling, you can't tell from their appearance if they are recycled secondary batteries? You can tell from the cost that they are black? .Heart Battery18650 batteries (grades A02~A04) produced by Samsung certified factories in mainland China cost around NT$12 for a 2200mAh unit (the price purchased by the factory in large quantities) and NT$360 for six 18,000 mAh units. units. If you add the cost of the PCB, the cost of returning to Taiwan, plus the manufacturer's 15% gross profit and the online shopping operator's 20% gross profit, plus the shipping cost of 35 yuan for consumers, the price of 18,000 mAh power bank should be at least (more than NT$800) is reasonable. ?
(Editor's note: Addiction Technology has spspecially invited Mr. Zeng Jiahui, a battery expert who has his own battery manufacturing factory and even his own battery formula, to share his professional knowledge of mobile power supply in a series of columns. In addition to making everyone understand, users who want to buy a safe and reliable power bank can also buy a power bank produced by Mr. Zeng)
Batteries Lithium Dongguan are not scammers. Dongguan lithium batteries are legal and have been examined by relevant departments. The production value of lithium batteries in Dongguan City reached 21.8 billion yuan in 2020, a year-on-year increase, ranking first in Guangdong Province, and is l one of the industries with the greatest development potential in the province. In addition, Dongguan city also hasnt abundant lithium resources, providing sufficient raw materials for the lithium battery industry. Therefore, Dongguan lithium battery industry is not a scam, but a real industry based on the advantages of Dongguan lithium resources.
