                                            Comparative Summary

(1) From the perspective of application scenarios

• Cylindrical battery: suitable for high-power, high consistency requirements scenarios such as electric vehicles, power tools, and energy storage systems.
• Square battery: suitable for scenarios with limited space and high energy density requirements, such as consumer electronics, electric vehicles, and energy storage systems.

(2) From the perspective of performance

• Cylindrical battery: high mechanical strength, good heat dissipation performance, suitable for high-power output.
• Square battery: high energy density, high space utilization, suitable for compact devices.

(3) From the perspective of manufacturing process

• Cylindrical battery: The manufacturing process is mature and suitable for large-scale production.
• Square battery: The manufacturing process is complex, but the design is flexible and suitable for customized needs.

(4) From the perspective of future trends

• Cylindrical battery: Large cylindrical batteries (such as Tesla 4680) combine the high consistency of cylindrical batteries with the high energy density of square batteries, and are expected to become mainstream in the future.
• Square battery: With the development of CTP (Cell to Pack) technology, the advantages of square batteries in energy density and cost will be further highlighted.

Summary:

• Cylindrical lithium battery: suitable for scenarios with high power and high consistency requirements, with mature manufacturing processes and good heat dissipation performance, but low space utilization.
• Square lithium battery: suitable for scenarios with limited space and high energy density requirements, flexible design, but complex manufacturing process and poor heat dissipation performance.

Which one is better?

There is no absolute superiority or inferiority, and the choice of lithium battery shape depends on the specific application scenario and requirements:

• If high power output and good heat dissipation performance are required, cylindrical batteries are a better choice.
• If high energy density and compact design are required, square batteries have more advantages.

In the future, with the development of large cylindrical batteries and CTP technology, cylindrical and square lithium batteries will continue to play an important role in their respective fields of expertise.
