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.
At present, there are three main types of mainstream lithium battery structures, namely, cylindrical, rectangular and pouch cells. Different lithium battery structure means different characteristics, and each has its own advantages and disadvantages. 1. The cylindrical lithium battery structure
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?
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.
Large-volume lithium-ion batteries such as electric bicycles and electric motorcycles are basically produced from cylindrical lithium batteries. Not only that, cylindrical lithium batteries are also recognized as green and healthy batteries. They are very environmentally friendly and can be used with confidence.
The round lithium battery refers to the cylindrical lithium battery. Because the history of the 18650 cylindrical lithium battery is quite long, the market penetration rate is very high. The cylindrical lithium battery adopts various mature replacement processes, the degree of automation is high, and the product mass transfer is stable.
