Column rechargeable battery

　　Advantages and disadvantages of the three packaging types of Column rechargeable battery

　　There are three main packaging types of Column rechargeable battery: cylindrical, square and soft package. Various packaging structures exhibit different characteristics and have advantages and disadvantages. Advantages and disadvantages of the three packaging types of Column rechargeable battery.

　　The first lithium battery packaging type: cylindrical lithium battery.

　　Cylindrical Column rechargeable battery can be divided into lithium iron phosphate batteries, lithium cobalt batteries, lithium ammonium sulfate batteries, lithium phosphate batteries, cobalt manganese batteries and three-dimensional materials. The key characteristics of Li-Fe-P rechargeable batteries at this stage are: large volume, high output voltage, good battery charging cycle time, stable output voltage, large battery charging current, stable catalytic oxidation characteristics, high operating temperature, and environmental protection. Used for solar street lights, lawn lights, energy storage devices, pneumatic tools, toy models, etc.

　　A standard cylindrical battery consists of a cover, a valve, a switching power supply component, a sealing ring, a positive phase, a negative phase, a protective film and a casing.

　　In 1992, Japan's Sony Corporation developed and designed the first cylindrical lithium battery. Because 18650 columnar Column rechargeable battery have a long history and a high sales market penetration rate. There are several specifications and models of cylindrical Column rechargeable battery such as 14650, 17490, 18650, 21700, and 26650.

　　The second type of lithium battery packaging: prismatic lithium battery.

　　Square Column rechargeable battery generally refer to aluminum-shell batteries or steel-shell rechargeable batteries. The popularity of square Column rechargeable battery in China is relatively high. In recent years, with the popularization of power Column rechargeable battery, the difference between mileage and power has become increasingly obvious. Most Chinese power lithium battery manufacturers choose to charge high-efficiency aluminum-cased square batteries. Because square batteries have a simple structure, they are different from high-explosion-resistant oil circuit boards and gas-pressure thick steel plates like covers, so the overall components are light. High characteristics. Square batteries use two different processing methods: loop and winding.

　　However, because prismatic Column rechargeable battery can be customized according to product specifications, there are various specifications and models sold on the market. However, due to the large size, the manufacturing process cannot be unified. It is not a problem for general electronic products to use grid rechargeable batteries, but for various serial communication or serial communication industrial equipment products, it is best to use standardized manufacturing of cylindrical Column rechargeable battery to ensure the smooth development of the process. Conveniently find removable and rechargeable batteries.

　　The third type of lithium battery packaging: soft package lithium battery.

　　Soft-packed Column rechargeable battery are a polymer shell of liquid Column rechargeable battery. The difference between soft-packed Column rechargeable battery and other rechargeable batteries lies in soft-packed plastic materials (composite plastic packaging products). The raw materials of plastic packaging products are generally divided into three layers, namely the outer resistance layer (usually the thickness of the surface protective layer made of polyester or polyester), the penetration layer (inner platinum) and the inner layer (high-precision layer).
