How to Model Short Circuits in Lithium-Ion Batteries
If a foreign metallic object penetrates the battery pack, or if the battery pack is damaged by being squashed, it can provide an internal conduction path that creates a short circuit. One standard safety test for lithium-ion batteries is the "nail test", in which a nail is driven into the battery to create a short circuit.

961016141-01A_Li-ion_Battery_UM_SAA_v1_d1
A battery pack will short circuit if a metal object makes a connection between the positive and negative contacts on the battery pack. Do not place a battery pack near anything that may cause a short circuit, such as coins, keys or nails in your pocket. Do not allow fluids to flow into battery pack.
Why do rechargeable batteries have no short-curcuit protection?
Bare cells can have basic protection integrated directly into them, like a PTC fuse or meltable separator, while a pack might have a more elaborate circuit. Some of these mechanisms are reversible when the short goes away and some are not.
