Should I make LiFePO4 Battery Compression？

Do I need to do LiFePO4 battery compression? This is a question that many customers who have purchased LiFePO4 batteries will have. And recently, the momentum of DIY LiFePO4 batteries is very strong, more and more people are starting to join the ranks of DIY, and this problem is mentioned more and more times. Whether the battery is compressed or not will actually affect the service life and performance of the entire battery pack.

Since LiFePO4 cells are sold individually, and most people will buy several LiFePO4 cells for DIY, the operation of battery compression is also included in the consideration list of most people. At present, the production specifications of most LiFePO4 battery manufacturers do not clearly state whether battery compression is required, and of course, they do not tell you how to compress. But after many people&#;s tests and suggestions from relevant professionals, there is no doubt that LiFePO4 battery compression is the best choice.

First of all, it is very important to do battery balancing first. After that, you need to prepare some tools that can be used for fixing, such as electrical tape, VHB tape, hose clamps. Then you need to prepare some insulating boards and thin sponges (1~2mm thickness). Then you need to arrange your LiFePO4 batteries in the way you want to connect, during this period, you need to put insulating sheets and thin sponges between each cell. The next step is to firmly bond the LiFePO4 cells together using the above-mentioned fixing tools and then start installing the busbars or wires. Once everything is done, place the entire battery pack into an appropriately sized insulated stand or insulated container for a final compression of the entire battery pack. According to this process, the LiFePO4 battery compression is completed. Of course, if you don&#;t have a suitably insulated bracket, you can make one yourself. You only need a simple plastic plate, studs, and nuts to complete a simple bracket.

3.  Due to the influence of the swell, the distance between each cell will become larger and larger, and the busbars of the battery will also be deformed due to the increase of the distance between the cells, thus affecting the normal operation of the battery pack. If the swell is serious, It may even damage the battery terminals.

LiFePO4 battery compression is an operation that should be done at the beginning of the purchase of the battery, and if the LiFePO4 battery pack after a period of use wants to make up for it, it is actually too late, because, after many charges and discharges, it may not be possible to intuitively It was found that the battery was different, but in fact, each battery cell was deformed to varying degrees, and it was no longer suitable for compression at this time. Therefore, LiFePO4 battery compression is a very important thing. Correct operation can make your battery stay with you for a longer time, and you can also get a better experience from it.

Why do I need to compress the LiFePO4 battery cells?

It is to prevent delamination of the internal components.

Delamination can lead to reduced battery life and additional stress on the electrical terminals.

Internal forces are constantly acting on the thin aluminum case, which is not strong enough to resist these forces.

Lack of compression can lead to LiFePO4 battery cells damage such as swelling and premature battery failure.

Properly increasing external pressure can effectively extend the life of LiFePO4 battery cells.

This is also evident from the specification of the EVE LF280N.

The standard test environment is conducted under a 300kgf fixture.

How to make a cell compression fixture

There are two easy way for DIY fixtures.

1, Using short boards and tapes

You can use a wooden board or hard plastic board as the end plate.

Use the tape to lock the cell cells first.

Then put the board/hard plastic board on both sides together and lock it with tape.

2. Threaded Rods and End Plates

Threaded rods can be purchased at your local hardware store.

Use threaded rods and end plates to tighten the battery.

You can also add coil springs, additional reinforcement and many other methods to create a smoother and more uniform compression fixture.
