Inorganic solid electrolyte materials have great potential to overcome the issues of conventionally used organic liquid electrolyte materials in lithium ion batteries. Garnet-structured Li7La3Zr2O12 based solid electrolyte materials having high ionic conductivity, good thermal and electrochemical stability and most importantly excellent stability with respect to lithium metal anode seems to be the most promising candidate to be applied in all solid-state lithium ion batteries. Garnet-structured electrolyte materials synthesized by conventional solid-state reaction method requires intermittent grinding and calcination steps along with sufficiently high temperature and long time for sintering. A significant amount of lithium is lost during this lengthy synthesis process, resulting in lower ionic conductivity and bulk density. Since these two factors play the most important role in the performance of an electrolyte, therefore, some other synthesis methods are required, which help in enhancing the performance of Li7La3Zr2O12 based electrolytes and also are easy to operate, ecofriendly and cost effective. Here an overview of the various synthesis methods has been provided and their feasibility for Li7La3Zr2O12 based solid electrolyte material preparation, in the context of their ionic conductivity enhancement and commercial applicability have been reviewed.

各种合成技术对石榴石结构固体电解质材料电输运性能的影响

无机固体电解质材料具有克服锂离子电池中常规使用的有机液体电解质材料的问题的巨大潜力。石榴石结构的 Li 7 La 3 Zr 2 O 12具有高离子电导率、良好的热和电化学稳定性以及最重要的是对锂金属负极具有优异稳定性的固体电解质材料似乎是最有希望应用于全固态锂离子电池的候选材料。采用传统固相反应法合成的石榴石结构电解质材料需要间歇性研磨和煅烧步骤以及足够高的温度和长时间进行烧结。在这个漫长的合成过程中会损失大量的锂,导致离子电导率和堆积密度降低。由于这两个因素对电解质的性能起着最重要的作用,因此需要一些其他的合成方法,这有助于提高 Li 7的性能基于La 3 Zr 2 O 12的电解质,而且易于操作、环保且具有成本效益。这里概述了各种合成方法,并在其离子电导率增强和商业适用性的背景下,审查了它们制备基于Li 7 La 3 Zr 2 O 12的固体电解质材料的可行性。
