Description

LGPS陶瓷片及其制备方法、LGPS陶瓷片的压制模具
技术领域
本发明涉及固态电解质的制备技术领域，具体涉及一种LGPS陶瓷片及其制备方法、LGPS陶瓷片的压制模具。
背景技术
相对于液态锂电池来说，固态锂电池具有更高的能量密度和更好的安全稳定性，被认为是下一代电池体系的重要候选者。其中，固态电解质是全固态锂电池的核心部件。根据电解质的成分区分，电解质分为聚合物固态电解质和无机固态电解质。得益于自身高的锂离子电导率，良好的稳定性，无机固态电解质成为固态电解质重要的开发目标。然而，由于无机固态电解质内部晶界阻抗大以及电极/电解质之间界面阻抗高，导致无机固态电解质实际锂离子电导率低的问题。这个缺陷制约了全固态锂电池的发展，造成了电池差的电化学性能，限制了锂离子电池能量密度的发挥。
一直以来，国内外很多研究者通过元素替换和掺杂的方式来改善离子导电通道以及填隙离子或离子空位的浓度，提高无机固态电解质自身的离子电导率。然而，无机固态电解质材料的性质很大程度上取决于晶界的密度，较大的晶界电阻势必会降低无机固态电解质的离子电导性能，因此，调控晶界的微结构是从材料形貌角度提高离子电导率的关键。目前来讲，针对无机固态电解质，往往通过高温来影响晶界。虽然高温处理能够有效减少晶界处的气孔数目，提高晶粒间的接触，但是高温处理一方面能耗较高，另一方面经常会导致样品的非晶化或玻璃化，不仅破坏了材料的晶体结构，反而使得材料的电导率降低。
发明内容
有鉴于此，本发明提供了一种LGPS(Li10GeP2S12)陶瓷片及其制备方法、LGPS(Li10GeP2S12)陶瓷片的压制模具，本发明提供的制备方法，无需经过高温过程，且制备得到的Li10GeP2S12陶瓷片具有较高的电导率。

实施例1～7
油压机事先预设压力设置分别为0.5、1.0、1.5、2.0、2.5以及3.0GPa，升压速率和保压时间统一设置为0.5GPa/min和5min。
取300mg粒径为0.2μm的Li10GeP2S12陶瓷片粉末在真空手套箱内放入图1所示结构的模具中，(模具预先放置于Cr钢垫块)，在10MPa下进行预压成型，然后将装载完样品的模具放入密封盒后从真空手套箱取出置于油压机按照预设加压程序进行压制成型，压制成型后进行退压，然后用脱模件将陶瓷片脱模，分别得到不同压制压力下的厚度1mm，直径16mm的Li10GeP2S12陶瓷片(简称为LGPS)。
对比例1
