Sigma-Aldrich 过氧化锂，99.9%微量金属，电池级

产品概述

Our battery grade lithium peroxide product is a high-purity material. It meets a minimum purity of 99.9%, as determined by trace metals analysis, and is processed to a particle size after passing through a sieve with 100-mesh openings, roughly 150 microns in diameter.


Lithium peroxide is an inorganic compound with the composition Li₂O₂ that takes the form of a white powder. Chemically, lithium peroxide is strongly basic and a powerful oxidizing agent. At room temperature, it is stable in air, showing neither hygroscopic properties nor a tendency to absorb carbon dioxide. At elevated temperatures in air, Li₂O₂ and CO₂ establish a reversible chemical equilibrium with lithium carbonate and oxygen. At even higher temperatures, ~340-450 °C, lithium peroxide decomposes to lithium oxide (Li₂O) and oxygen gas.




Lithium Peroxide is a key material in lithium-air batteries, offering high energy density and efficient oxygen storage. Its use supports greener technologies by enabling lightweight, long-lasting batteries with reduced environmental impact, advancing sustainable and high-capacity energy storage solutions.

应用领域

我们的高纯度过氧化锂的主要用途是作为合成前体生产高纯度氧化锂和其他锂金属氧化物。在电池研究中，过氧化锂是锂金属氧化物的关键前体，特别是具有无序岩盐结构的富锂氧化物，可用作锂离子电池的阴极材料。过氧化锂通常用于机械化学反应，其中过氧化锂与一种或多种金属氧化物一起球磨，然后在高温下烧结。在此应用中，我们的过氧化锂的微量金属纯度至关重要，因为前体的纯度直接影响最终产品的纯度。此外，由于其高重量氧含量和易于氧化还原的化学性质，过氧化锂也用于空气净化器中以去除二氧化碳，最显著的是在航天器上，当重量很重要时。过氧化锂与二氧化碳可逆反应形成碳酸锂和氧气也是锂-空气电池的化学基础。
