Intermetallic lithium compounds have found a wide range of applications owing to their light mass and desirable electronic and mechanical properties. Here, by compressing pure lithium and zinc mixtures in a diamond-anvil cell, we observe a direct reaction forming the stoichiometric compound LiZn, at pressures below 1 GPa. On further compression above 10 GPa, we observe the formation of Li₂Zn, which is the highest lithium content compound to be discovered in the Li–Zn system. Our results constrain the structures of these compounds and their evolution with pressure, furthering our understanding of potentially useful light volume-efficient energy storage materials.

高压下锂锌化合物的结构

金属间锂化合物由于其轻质和合乎需要的电子和机械性能而已发现了广泛的应用。在这里，通过在金刚石-铁砧电池中压缩纯锂和锌的混合物，我们观察到在低于1 GPa的压力下会形成化学计量的化合物LiZn的直接反应。在10 GPa以上的进一步压缩下，我们观察到Li ₂ Zn的形成，这是在Li–Zn系统中发现的锂含量最高的化合物。我们的结果限制了这些化合物的结构及其在压力下的演化，从而加深了我们对可能有用的光体积效率高的储能材料的理解。
