Lithium is water-reactive. This is why a cell phone will erupt into flames if the long flat cell inside is punctured. When punctured, the lithium is exposed to the air and it will react with the water content in the air.
I think it isn't that such an amount of water is needed to extinguish the lithium fire, it is that so much water is needed to constantly fuel the lithium to get it to burn itself out while also constantly saturating surrounding materials to lessen their likelihood of igniting so only the lithium burns.
