Material between compressed cells

[Johneb]

Okay I have searched but not found an answer to this question. I have read somewhere of putting a thin sheet of aluminum between cells before compression with the sheets extending out the sides to dissipate heat from the cells. If you are careful to not get the aluminum above cell height, would this work or be advisable? My setup will be in a truck camper battery box. It does have vents but I imagine it could still get very warm in there. I plan to add cooling fan(s) with temp sensors to turn them on and off as needed.

be advisable

No. If anything, you want something non-conductive.

Some threads with ideas....

Compression material thoughts...

While waiting for my Lishen 272ah that will be in a 16s configuration, I’ve been thinking about all the “fixture” information and materials. Going through material to place in between cells, I came across this and wanted to get your guys’ thoughts...

What material to use in between prismatic cells

Folks, what material should I put in between prismatic cells when making 16s pack? Neoprene, Polycarbonate or something else if you can recommend? Is this even necessary?

LiFePO4 Cell Separator Material

What can I use to separate my LFP Cells and/or line my metal box with to protect my cells ? There are many creative solutions and yet some are downright dangerous (incorrect material for task). The "PROPER" Material for such an application is Epoxied Fiberglass Sheets, specifically, FR-4...

,Okay, got it.

Regarding battery compression, a non-conductive separator (or sponge) needs to be placed between the cell and the cell, but it should be noted that the separator should not be too thick.

Amy from Luyuan will sell you insulation material that they are using and I'm pretty sure Docan has something similar as well.

I used electronic fish paper.

Also pad battery pack bottom with anti-vibration pad.

That's fine, insulation is important.

I used concrete board wrapped in parchment paper between cells, in a compression pack. It's cheap, cuts easily with a diamond blade in a skill saw, and should be a good fire barrier. But you have to make the interconnects.

On the other hand I don't have this really working yet, although the problems have nothing to do with using the concrete board. But no track record.
