It's a minor detail that people generally don't talk about - if you overcharge a Li-Ion (or Li-Po) cell, it is very likely to "Vent with flame".
Short-circuits can have the same effect as well!
Inside every commercially-available Li-Ion battery pack there is a charge-monitor IC and thermal fuse system that tries to prevent this - that "Fuel Gauge" on your laptop isn't only there for your convenience - it's there to protect your loins as well!
