Power cylindrical lithium battery

Power cylindrical lithium batteries are a crucial component in the electrification of transportation and consumer electronics, 

offering a combination of high energy density, reliability, and safety features tailored to meet the demands of modern 

applications,known for their high energy and power density, extended life cycles, and widespread use in various applications.


Design and Structure: 

Cylindrical lithium-ion battery cells consist of a "jelly roll," which is a wound composite of cathode, anode, and two separators, 

housed within a cell casing that includes a can and a cap. The jelly roll design helps in efficient current and heat transport 

between the electrodes and the cell housing.


Standardization and Industrialization:

Cylindrical batteries are characterized by a high degree of standardization and have the longest development history among 

lithium-ion battery formats. This standardization and advanced winding technology make them extensively used in diverse 

applications, such as portable electronics and EVs, with common models like18650, 26650, and 21700 being prevalent.


Heat Dissipation: 

One of the notable advantages of cylindrical batteries is their superior heat dissipation under fast charging conditions due to 

the ample spacing between individual cells when packaged. This is in contrast to pouch or prismatic battery designs.


Safety and Reliability: 

Safety is a critical aspect of lithium-ion batteries, and cylindrical batteries have been designed with various safety features, 

such as vent balls for internal pressure release and Positive Temperature Coefficient devices for overcurrent protection . 

Studies have been conducted to improve the reliability of lithium-ion batteries based on statistical analysis and cluster 

analysis, focusing on the failure mechanisms and consequences.


Applications: 

Cylindrical lithium-ion batteries are used in high-drain applications, providing greater service advantages over other primary 

battery types at low temperatures, higher operating voltage, and superior leakage resistance. They are also used in EVs to 

overcome air pollution and provide an alternative to fossil-fuel transportation.


Production and Assembly: 

The production of cylindrical lithium-ion batteries is divided into three main steps: electrode production, cell assembly, and 

cell formation and finishing. The assembly techniques differ significantly between cell formats, with cylindrical cells having

distinct methods involving the use of tabs for current and heat transport.
