Lithium-ion batteries don't contain raw lithium. It's got the same explosive reactivity as the sodium in salt. Water is a good way of stopping thermal runaway through cooling. Lithium batteries on the other hand do contain raw lithium and thus will react with water. These types of batteries aren't used in phones though.
