Cylindrical lithium-ion battery cells are a type of rechargeable battery commonly used in a wide range of electronic devices, electric vehicles, and energy storage systems. They are characterized by their cylindrical shape, standardized sizes, and high energy density, making them versatile and suitable for various applications.
The structure of cylindrical lithium-ion cell The round lithium battery refers to the cylindrical lithium-ion cell. The earliest cylindrical lithium-ion cell was the 18650 lithium battery invented by the Japanese company SONY in 1992. Due to the long history of the 18650 cylindrical lithium-ion cell, the popularity of the market is very high.
There are many types of cylindrical cells, such as 14650, 17490, 18650, 21700, 26650 and so on. Cylindrical lithium batteries are more prevalent in Japanese and Korean lithium battery companies, and there are also companies of appropriate scale in China that produce cylindrical lithium batteries. Ⅲ.
Due to the long history of the 18650 cylindrical lithium-ion cell, the popularity of the market is very high. The cylindrical lithium-ion battery adopts an appropriate and mature winding process, with a high degree of automation, stable quality of the cylindrical lithium-ion battery, and relatively low cost.
For instance, “65” represents a height of 65mm. Fifth Digit: The fifth digit indicates the cylindrical shape of the cell. Typically, it’s “0” for cylindrical cells. By following this naming convention, we can easily identify the size and shape of cylindrical lithium-ion battery cells.
The naming rules for cylindrical lithium-ion battery cells follows a standardized format based on the cell’s dimensions, and usually represented by a five-digit code, where each digit provides specific information about the cell’s dimensions. Here’s a breakdown of the representation: What does 18650 means?
