There’s a lot of energy in there.
If you cause a short through the whole thing, instead of nicely providing 5v for a long duration, it’s all the volts all at once. That flow of electricity heats up everything acting as a resistor along the path, just like a space-heater but uncontrolled. Whatever the electricity is flowing through can heat up so much that it vaporizes. Gases forming inside of solids can build up pressure and explode really quickly.
