There's quite a bit of difference in energy content - as well as the number of cells, and with that the risk of failure - between an ebike battery and a phone or similarly sized item.

It's the difference between the general and the specific.
Keeping a battery reasonably cool is generally a good idea. A certain amount of heat build-up mainly accelerates ageing - number of charge/discharge cycles a bit. But with a suitable charge rate the battery shouldn't cook anyhow.
However, good ventilation isn't that good protection against (the layers in a) single cell shorting out, overheating and bursting.
