Thermal Runaway can happen. The battery can''t physically/chemically store the energy if delivered too fast, so it is dissipated as heat. Contrary to what some comments/answers may suggest, the charger needs to be told the maximum current to deliver. They normally don''t/can''t ''sense'' it.

If I charge a battery using a much higher current, can it explode?

Supposing that the charger gives the voltage greater than 12 V (say, 15 V), we can estimate 15 V × 100 A = 1500 W, a power of a small electric kettle. It is insufficient to effect an actual explosion quickly, but the battery will possibly immediately start to spew the acid mixed with hydrogen bubbles (note that hydrogen is flammable).

What happens if you charge a battery with too much current?

The standard 0.1C rate is a compromise between battery life and charging practicality: it is slow enough not wear or heat up the battery during charging, but fast enough to fill an empty battery overnight. If charging time is not an issue, charging rates much under 0.1C can also be used.

Connecting a higher-current power supply to a lithium-ion charger

If the USB adapter can''t provide that much power, the device charges the battery at a lower rate. For most devices, the charging rate doesn''t go above 1C regardless of how much power the USB adapter can provide, because the the battery charger circuit inside the device also limits current into the battery. $endgroup$ –
