I'd image that is why a lot of the Chinese battery OEM is moving ttowards safer chemistry, not for the clout, but because there is some rather large supply chain costs when your 0.1% yield rate makes it into the finished product of a vendor.
>is it really saferIts still 50-70KWh per car, that is still some ~45-60kg of TNT per car that shorts, even if the car fizzles like a spark shower and the TNT goes boom. But not shorting on puncture is a major benefit, similar to how a lot of cars is going to have reinforced gas tanks if the car fails the initial safety tests
