Hi Tom,
a belated comment.
When talking about companies that had to address a battery issue you mentioned Tesla Motors. However, in the case of Tesla motors the battery itself was not the issue, and the subsequent design change wasn’t to the battery.
There were a couple of incidents where very heavy road debris that the car had ran over had penetrated into the battery pack, and the damage resulted in a runaway reaction and subsequent fire.
The existing armour for the battery pack was already very strong, something like a boulder would always bounce off, but in one of the incidents an elongated and relatively sharp heavy object had been kicked up so violently that it had penetrated into the battery pack.
The design change: addition of “Titanium Underbody Shield and Aluminum Deflector Plates”

Incidentally, earlier this year there was a case of a runaway battery reaction in France. During a normal drive the car’s computer issued an overheating alarm. The driver brought the vehicle to a stop, and the occupants got out of the car. Some minutes later flames erupted.

It’s a fair point. Tessa’s situation was not the same as Samsung’s. While the fault may not have been Tessa but my point is that lithium ion batteries are tricky and prone to problems.
