Pouch cell is a specific shape of lithium-ion battery characterized by the use of flexible polymer materials as the outer packaging inside the battery, instead of the traditional metal shell. This flexible outer packaging allows for flexible design in shape and size as needed, hence the name soft pouch cell. Soft pouch cells typically consist of multiple layers of thin film materials, including active materials for the positive and negative electrodes, electrolytes, and separators. These layers of materials are stacked and encapsulated layer by layer to form a flexible and sealed battery structure.
Characteristics of Pouch Cells:
Flexible Design: Due to the use of flexible polymer materials, pouch cells can be designed into various shapes according to the requirements of electronic devices or applications, maximizing the use of available space and adapting to complex product designs.
High Energy Density: Optimized design and manufacturing processes enable pouch cells to achieve higher energy density, providing longer usage time and higher power output. This is particularly crucial for electric vehicles and portable devices.
Lightweight: Compared to traditional metal casing batteries, pouch cells are typically lighter, contributing to overall weight reduction in devices, especially advantageous in applications requiring lightweight designs.
Good Heat Dissipation: pouch cells, due to their flexibility and larger surface area, can dissipate heat more effectively, enhancing battery thermal management and extending battery lifespan and stability.
