Seeing as Li-Ion short circuits tend to involve copious amounts of current, lots of heat is usually generated too, and heat + Li-Ion electrolyte = boiling and fire, and once air gets in, the Lithium catches fire too. 4.2V just happens to be the voltage required to fully charge a Li-Ion battery and any more voltage will start to cause unwanted side reactions.

Overvoltage protection and undervoltage protection are essential features in battery management systems (BMS) designed to maintain battery health and safety.
Figure 1 shows an ultralow power, precision undervoltage-lockout circuit. The circuit monitors the voltage of a Li-Ion battery and disconnects the load to protect the battery from deep discharge when the battery voltage drops below the lockout threshold.
Over-discharge is when voltage is drained from the battery cell to below two volts. Undervoltage is a condition that originates from storing the battery for a long time without use until the voltage goes below 2 V per cell. These two conditions lead to a breakdown in the anodes and cathodes.
Most EVs with LiIon batteries have less than 4.2V maximum charge voltage and recommend charging up to 80-90% of available capacity when possible. (Source: my ID.4 owners manual) I also know that charging a lithium ion battery involves a constant current and constant voltage phase. It usually does, but it's not necessary.
