Lithium ion batteries are batteries made from non-aqueous electrolyte solutions using lithium metal or lithium alloy as the negative electrode material. Lithium metal batteries were first developed and studied by Gilbert. Lewis was born in 1912. In the 1970s, Watson proposed and began researching lithium-ion batteries. Due to the highly reactive chemical properties of metallic lithium, the processing, preservation, and use of metallic lithium have high environmental requirements. Therefore, lithium-ion batteries have not been used for a long time. With the development of technology, lithium-ion batteries have become mainstream and are widely used in various electronic and digital products. So what about lithium-ion batteries?

Look at the appearance

Looking at the appearance refers to the appearance, process, size, and process of lithium-ion batteries. Check if the seam width of the shell is wide, if there are burrs, oil stains, and good hand feel. Advanced technology makes the hand feel very comfortable. After polishing, the rubber polish material not only has a good hand feel, but also has strong insulation performance.

Check if the capacity is clearly marked

Lithium ion batteries without clear capacity markings are likely to be garbage batteries using inferior batteries or batteries reassembled from recycled batteries. There are many cheap lithium-ion batteries on the market, which are made from recycled or dismantled batteries. Although the price is cheap, the service life is short, the quality is unstable, and careless use may damage the equipment and even cause explosions.

Look at the protection circuit

The characteristics of lithium-ion batteries determine that they must be equipped with protective plates to prevent overcharging, discharging, and short circuits from occurring. Without protective plates, lithium-ion batteries pose a risk of deformation, leakage, and explosion. Faced with fierce price competition, battery packaging companies are seeking cheaper protective circuits or simply not buying such devices, leading to the market being flooded with potentially explosive lithium-ion batteries. Of course, in fact, consumers cannot differentiate the protection of circuit boards from their appearance, so it is best to choose reputable merchants to purchase.

Look at the brand

There are many brands of lithium-ion batteries, but it is difficult to see the quality from the appearance. In this case, everyone should do more homework before choosing and check the manufacturer's information online. Generally speaking, professional companies are more reliable than small ones, and companies with a long history are more reliable than companies newly entering this field.
