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
Abstract In engineering applications such as electric vehicles and energy storage systems, the structural safety of cylindrical lithium-ion batteries is crucial, especially under external impact or compressive loads that may induce deformation or damage, affecting overall safety performance.
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.
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.
Rectangular lithium battery usually refers to an aluminum shell or steel shell rectangular battery. The expansion rate of the rectangular battery is very high in China. It is the rise of automobile power battery in recent years. The difference between vehicle cruising range and battery capacity is becoming more and more obvious.
