Home Computer Audio Asylum

Music servers and other computer based digital audio technologies.

Not to belabor the Samsung issue, but...

LiFePO4 cells for phones/tablets are often in flexible foil packs, so they're easier to shoehorn into weirdly shaped places.

Cell expansion is well known and gets accounted for. Some surmise that it was the fast charging algorithm that put more stress on a cell, causing the electrolytes to heat up, vent some gas perhaps and expand the physical dimensions, not causing any shorts.

Problem is is that they'd have (and have) already tested this before and known that at a .5C (C=capacity of cell X) charge rate, the cell will be fine. At a 1C charge rate, mild heat and some expansion, at a 1.5C rate, expansion easy to detect and measure and finally, at a 2C rate, cell pouch ruptures due to heat/gas build up.

So...let's keep the charging rate down to a .75C rate as a fast charge option and be fine?

Anyhow...maybe there were some shenanigans?
