I worked at a lithium ion battery company for 11 years. Water won’t do it. When ruptured, a lithium ion battery goes into something called thermal runaway. You need to use CO2 fire extinguishers to cool the batteries to get the fire to stop. Otherwise, it will burn until all the energy is used up. I suppose it’s possible to use water that’s cold enough to stop the reaction, but I highly doubt it.

Water turning into steam soaks up an enormous amount of heat. I assume that thermal runaway happens somewhere above 100C, right?
CO2 extinguishers work by displacing oxygen, not by cooling.
The rapidly expanding co2 does get very cold though. It’s not any different from freezing things with compressed air cans.
I don’t hover, know which would absorb more heat per pound though. Someone who knows more math than I can do it though.
