Lithium-ion batteries have become one of the main chemical power sources today due to their high energy density, long cycle life and environmental protection. There are three main packaging forms in the production and manufacturing of lithium-ion batteries: prismatic lithium battery, cylindrical lithium battery and pouch cell lithium battery.
I. Structural Characteristics of the Three Batteries
- Prismatic lithium battery: Uses an aluminum or steel shell for packaging, and the internal structure can be designed according to needs, with high energy density.
- Cylindrical lithium battery: The shape is like a cylinder, which is easy to produce and manufacture, and has low cost.
- Pouch cell lithium battery: Packaged with aluminum-plastic film, light weight, small volume, and good plasticity.

III. Future Prospects of the Three Batteries
-
- Prismatic lithium battery: With its advantages of high energy density and safety, it is expected to dominate the power battery field.
- Cylindrical lithium battery: Due to its low cost and ease of manufacture, it will still have a vast market in the field of consumer electronics.
- Pouch cell lithium battery: Benefiting from its light and thin characteristics, it has great development potential in wearable devices and other fields.
IV. Conclusion
Prismatic lithium battery, cylindrical lithium battery and pouch cell lithium battery each have their own advantages and disadvantages, and are suitable for different application fields. With the progress of technology and the reduction of costs, the application range of lithium-ion batteries will be further expanded and play a more important role in energy transformation and sustainable development.
