Lithium battery shape classification analysis

1. Cylindrical lithium batteries were designed and manufactured in cylindrical shapes when the batteries were first developed and manufactured. This kind of battery is the most widely used, like 18650 lithium battery, 26650 lithium battery and so on. Like the early laptop battery, it is generally composed of eight 18650 batteries. The cylindrical lithium battery has a high degree of standardization, and it is easy to achieve a unified standard in the industry. In addition, cylindrical batteries also have inherent advantages in terms of heat dissipation. When packaging, a good heat dissipation space is formed between the cylinders and the cylinders. 2. Square lithium batteries Most square batteries are polymer lithium batteries because of the good ductility of polymers. The reason is that many shapes can be made, and the length, width and height of the lithium battery can be adjusted at will. Many digital products currently use this battery product. The plasticity of the prismatic battery will be stronger, and the design can be customized according to the detailed requirements of the carried product. This has also led to different sizes. At present, regardless of the manufacturing process or use standards, there is no clear standard division as for cylindrical batteries. 3. Button-type lithium batteries Button-type lithium batteries actually meet the needs of computers, cameras, and notebooks for high specific energy and thin profile. Many corresponding commercial companies are engaged in battery development in this area. Button-type lithium batteries are mainly used in computer motherboards, MP3 watches, calculators, IC cards, electronic dictionaries, tax control machines, Bluetooth headsets, hand-cranked rechargeable flashlights, toy walkie-talkies and other products. Good use temperature, good sealing performance, long storage time, stable discharge voltage and many other advantages. 4. Abnormal-shaped lithium battery Abnormal-shaped lithium battery is also a battery trend. Many companies’ products must highlight their own magic and differences and specially design their own batteries. These batteries are all odd shapes. For example, if the bracelet is ring-shaped, it is possible to make the battery into a ring to fit the bracelet. In many cases, military products also have a certain demand for this aspect. 5. Soft-pack battery The soft-pack battery is thinner and has the highest energy density because of the overlapping manufacturing method, which is more in line with the development trend of my country's new energy vehicle market. In addition, the soft pack battery can also be customized according to different needs. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
