Lithium Reacting with Water

2Li + 2H2O → 2LiOH + H2

概述

Lithium reacts steadily with water to produce lithium hydroxide and hydrogen gas. While still vigorous, lithium is the least reactive of the alkali metals due to its high ionization energy and strong metallic bonding. The hydrogen does not ignite spontaneously as with sodium or potassium.

日常示例

Lithium's moderate water reactivity is why lithium-ion batteries, while reactive, are generally safer to handle than metallic sodium or potassium.

工业重要性

氢氧化锂是制备高镍三元锂离子电池正极材料（NCM811、NCA）的关键前体，也用于航天器和潜艇的CO₂吸收剂，随新能源汽车产业快速发展需求激增。
