COMPRESSION CASE FOR BATTERIES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18100507 titled 'COMPRESSION CASE FOR BATTERIES
The abstract of the patent application describes the use of expanding foam to provide stack pressure for battery cells, specifically solid-state pouch cells.
- Battery units are provided with battery cells within a casing, where expanding foam is introduced to fill the internal volume and apply stack pressure on the cells.
- The expanding foam expands to substantially fill the remaining portion of the internal volume, ensuring proper pressure on the battery cells.
Potential Applications:
- This technology can be applied in various battery systems to improve performance and safety.
- It can be used in electric vehicles, portable electronics, and renewable energy storage systems.
Problems Solved:
- Ensures proper stack pressure on battery cells to enhance performance and longevity.
- Provides a cost-effective and efficient solution for maintaining battery cell integrity.
Benefits:
- Improved battery performance and longevity.
- Enhanced safety and reliability of battery systems.
- Cost-effective solution for battery manufacturing.
Commercial Applications:
- This technology can be utilized by battery manufacturers, electric vehicle companies, and electronics manufacturers to enhance the performance and safety of their products.
Prior Art:
- Prior research may include studies on stack pressure management in battery systems and the use of expanding foam in various applications.
Frequently Updated Research:
- Ongoing research may focus on optimizing the composition and expansion properties of the foam for different battery cell configurations.
Questions about the technology: 1. How does the expanding foam impact the overall performance of battery cells? 2. What are the potential challenges in implementing this technology in large-scale battery production?
Original Abstract Submitted
Aspects of the disclosure relate to the use of an expanding foam to provide a stack pressure for battery cells such as solid-state pouch cells. In one or more implementations, a battery, a battery unit, a battery module or a battery pack is provided with one or more battery cells within an internal volume of a casing. An initial volume of an expanding foam is introduced into the internal volume, and allowed to expand to substantially fill a remaining portion of the internal volume and to provide the stack pressure on the battery cells.
