A generic overview of designing cylindrical Li-ion battery cells. Function 1: Two types of jelly roll designs can be distinguished: With tabs and tabless. Jelly rolls with tabs can be realized with a single tab (Design A) or several tabs in a multi-tab design (Design B).
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.
This work is motivated by the critical need to improve the thermal stability of cylindrical lithium-ion batteries, especially in electric vehicles and high-performance electronics, where overheating during rapid charging and high discharge rates can lead to thermal runaway and decreased lifespan.
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.
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.
