A lithium anode is expected to be applied to next-generation batteries using inorganic solid electrolytes (ISEs). When joining Li with ISEs, interfacial reactions often cause performance degradation and have been avoided. In this report, we demonstrate a new strategy for the ultrafast formation of a good interface between Li and ISEs, using a reactive process (ultrasonic-assisted fusion welding method). We found that ultrasonic irradiation helps in suitable interface formation between molten Li and ISEs, and the joining process finishes in just a few seconds. The obtained interface showed a low resistance and could be used under a high current density of 0.5 mA cm⁻². The development of prototype cells for next-generation batteries was promoted by this ultrafast process.

一种制备锂金属-无机固体电解质界面的超快工艺

锂负极有望应用于使用无机固体电解质 (ISE) 的下一代电池。将 Li 与 ISE 结合时，界面反应通常会导致性能下降，因此已被避免。在本报告中，我们展示了一种使用反应过程（超声波辅助熔焊方法）在 Li 和 ISE 之间超快形成良好界面的新策略。我们发现超声波照射有助于在熔融锂和 ISE 之间形成合适的界面，并且接合过程只需几秒钟即可完成。获得的界面显示出低电阻并且可以在0.5 mA cm ^-2的高电流密度下使用。这种超快工艺促进了下一代电池原型电池的开发。
