Enhancing the performance of ceramic solid-state electrolytes (SSEs) often relies on incorporating effective fillers. However, the choice of fillers is often limited to only a few highly stable ones, as the long-term sintering by conventional methods often leads to severe loss of volatile components. Herein, we develop an ultrafast sintering method for SSEs with volatile fillers toward a dense and high-performance membrane. Using Ta-doped Li₇La₃Zr₂O₁₂ (LLZTO) as a model system, we sinter a Li₃N/LLZTO composite SSE, which shows a higher relative density, a higher ionic conductivity, and a reduced electronic conductivity compared to the pristine LLZTO. In contrast, no Li₃N can be observed in the membrane sintered by a conventional furnace due to its high volatility. This study opens up a new route for the rational selection of fillers in a much broader space toward synthesizing high-quality and high-performance ceramic SSEs.

具有挥发性填料的固态电解质的超快烧结

提高陶瓷固态电解质 (SSE) 的性能通常依赖于加入有效的填料。然而，填料的选择通常仅限于少数高度稳定的填料，因为通过常规方法长期烧结往往会导致挥发性组分的严重损失。在此，我们开发了一种用于具有挥发性填料的 SSE 的超快速烧结方法，以形成致密和高性能的膜。使用 Ta 掺杂的 Li ₇ La ₃ Zr ₂ O ₁₂ (LLZTO) 作为模型系统，我们烧结了 Li ₃ N/LLZTO 复合 SSE，与原始的 LLZTO。相比之下，没有李₃由于 N 的高挥发性，可以在传统炉子烧结的膜中观察到 N。该研究为在更广阔的空间中合理选择填料以合成高质量和高性能陶瓷 SSE 开辟了新途径。
