I can't find what I read, It had graphs showing capacity vs time.
FYI i just spotted this article that discusses the pros and cons: "Note CON #3 which I did not know.
- Reduced reliability: In some cases, compressing the cells may actually reduce the overall reliability of the battery pack. This is because the compression process can increase the risk of internal shorts or other types of damage to the cells."
Pros of Compressing LiFePO4 Cells
The lithium battery industry has undergone tremendous growth in recent years, creating a need for more efficient and reliable batteries. A popular type of lithium battery is the Lifepo4 cell, which can be compressed to enhance its performance. Compressing cells results in longer battery life, faster charging time, easier storage and transportation due to the smaller size, increased power output, and reduced maintenance and lifecycle costs. Compression is not mandatory but can ensure long battery life if cell connections are strong and secure. If you want a longer-lasting battery and fewer problems, consider compressing your Lifpo Cells!
There are several potential benefits to compressing LiFePO4 cells, including:
- Improved electrical conductivity: Applying pressure to a battery cell can help to improve the electrical conductivity between the cell internal layers. This can lead to better performance and efficiency, especially in high-drain applications.
- Longer cycle life: LiFePO4 batteries are known for their long cycle life, and compressing the cells can help to extend this even further. This is because compression can help to prevent the electrode materials from foaming in the electrolyte, separating, cracking and forming over time, which can reduce the battery’s overall capacity.
- Increased safety: LiFePO4 batteries are already considered to be some of the safest lithium-ion batteries available, but compression can further enhance this safety by reducing the risk of thermal runaway or other types of battery failure.
Cons of Compressing LiFePO4 Cells
While there are certainly some potential benefits to compressing LiFePO4 cells, there are also a few potential drawbacks to consider, including:
- Increased cost: Depending on the size and complexity of your battery pack, compressing the cells may require additional materials and manufacturing processes, which can add to the overall cost of the battery.
- Decreased flexibility: Compressing the cells can limit the flexibility of the battery pack, making it more difficult to fit into certain types of devices or applications.
- Reduced reliability: In some cases, compressing the cells may actually reduce the overall reliability of the battery pack. This is because the compression process can increase the risk of internal shorts or other types of damage to the cells.
Compressed Cell Safety and Longevity Considerations
To start, it is vital to understand LiFePO4 battery technology and how compression works. Compressing LiFePO4 cells involves firmly combining multiple cells together to maintain consistent contact and prevent movement when faced with external forces, such as vibrations or shocks. Additionally, compressed LiFePO4 batteries maintain their performance and run for extended periods without degradation caused by cell swelling or delamination of internal components due to uneven stress on electrical terminals.
When evaluating whether to compress your LiFePO4 cells, safety risks and the expected lifespan of compressed versus uncompressed cells must be considered. Failure to compress your batteries can lead to cell swelling, increasing pressure inside the battery pack and causing potential short-circuiting. Uncompressed cells can also cause delamination of internal components and additional stress on electrical terminals over time. It is essential to understand any required regulatory changes before performing modifications to avoid exposing yourself or others to unnecessary risks during use.
Overall, compressing your LiFePO4 batteries according to manufacturer recommendations can be an important maintenance step. It helps ensure maximum performance while keeping you safe from potentially hazardous incidents resulting from improper handling practices in the future.
Should You Compress LiFePO4 Cells?
So, with all of that in mind, should you compress LiFePO4 cells? As with many engineering decisions, the answer will depend on your specific application and requirements. If you need the highest possible performance and efficiency from your battery, and cost is not a major concern, then compression may be a good option to consider. On the other hand, if you need a more flexible or cost-effective solution, then compression may not be needed.
