Pouch Film for Secondary Battery and Manufacturing Method Thereof - A simplified explanation of the abstract
This abstract first appeared for US patent application 18033628 titled 'Pouch Film for Secondary Battery and Manufacturing Method Thereof
Simplified Explanation
The abstract describes a pouch film for a secondary battery and a method for manufacturing it. The film includes a stretchable auxiliary layer with multiple layers having different elongation rates, which improves the moldability of the pouch and reduces the risk of breakage. This leads to reduced defect rates and manufacturing costs.
- The pouch film for a secondary battery includes a stretchable auxiliary layer with multiple layers.
- The layers in the auxiliary layer have different elongation rates.
- The stress at the interface of each layer is relieved, improving the moldability of the pouch.
- The risk of breakage of the pouch is significantly reduced.
- Defect rates in the pouch manufacturing process are reduced.
- Manufacturing costs are reduced as a result.
Potential Applications
This technology can be applied in the manufacturing of pouch films for secondary batteries used in various electronic devices, such as smartphones, laptops, tablets, and electric vehicles.
Problems Solved

Enhanced product reliability: The reduced risk of breakage ensures the reliability and longevity of the secondary battery. 3. Improved manufacturing efficiency: The improved moldability of the pouch film streamlines the manufacturing process, increasing efficiency.
Original Abstract Submitted
A pouch film for a secondary battery and a method for manufacturing the same. In some embodiments, the pouch film includes a stretchable auxiliary layer that is a multi-layered structure comprising a plurality of layers, wherein layers in the plurality of layers have different elongation rates. The stress at the interface of each layer is relieved and the moldability of a pouch is improved. The risk of breakage of a pouch is significantly reduced and defect rates are reduced in a pouch manufacturing process, thereby reducing manufacturing costs.
