I highly doubt there is any use for those batteries beyond been scrapped, do you want to own/touch anything that has the potential to literally spontaneous combust?? The worrying thing for LG is as far as I understand they still don't know the reasons for the fires apart from its thermal runaway!!! I believe GM has stopped Bolt production but LG are still putting the same packs into other cars??!!
Tesla went through a similar thing with the older 85kWh packs about 18 months ago, but because Tesla makes the pack and the cars they seem* to have solved the issue with changes to the BMS.
The Cells LG supply for the Bolt and Kona is whats in the iPace, ID3, eTron etc pretty much everything that isn't a Tesla or made in China.
Given chronicty is clearly an important factor in thermal runaway for all EVs the executives at LG must be bitting their nails at the moment. The iPace does seem to suffer from cell block failures- isolating the bad cell is much safer than burning the car.
*Tesla 85 packs are suffering higher rate of cell block failures than before, and at low mileages. I suspect the Tesla BMS is now super aggressive in disabling the car at any hint of cell block imbalance. The trend seems to be one warning, and within days the car essentially disables the entire traction battery whilst gradually reducing usable range, presumably allowing the owner to get home rather than been abandoned by the side of the road.
There are also reports when Tesla investigated their fires they found something fundamentally flawed with the 85 packs they didn't expect to find as the packs aged but have to date not disclosed that information to the public and have threatened to sue the few private individuals who knows what the issue is to keep them quite.
I also park my car well away from the house these days. EV fires may still be rare but it clearly is an issue, and may get worse before it gets better.
Batterygate 2.0 has the potential to make dieselgate look pathetic, in retrospect the signs where there even as early as 2015 with unexplained Tesla fires, but ignored by most (my self included).
The 2019 model-year Bolt inside a garage and the fire lightly damaged a pickup that was parked next to it.
