A lot of them will be fine but some of them are cheap knockoffs and they have unsafe wiring. It’s not actually the batteries themselves as they’ll probably be the same batteries it’s the way the batteries are connected up that makes them more likely to explode.
Unless you are Samsung in which case it 100% was the batteries at fault not the wiring.
It can also be due to unsafe charging (over-voltage) or unsafe discharging (over-current, generating too much heat). The actual fire doesn’t necessarily happen immediately during charging/discharging.
