Lithium-ion batteries can erupt in violent explosions and out-of-control fires, and toxic chemicals can be released rapidly.

The Chicago Fire Department is raising awareness about the increasing number of fires caused by faulty lithium batteries in the city.

The batteries appear to be victims of a catastrophic malfunction that can lead to overheating and even explosions.

"The people that buy those batteries are aware of that they are cheaper batteries, but they still take the risk.”
