Long processing time and high temperatures are often required in sintering ceramic electrolytes, which lead to volatile element loss and high cost. Here, an ultrafast sintering method of microwave-induced carbothermal shock to fabricate various ceramic electrolytes in seconds is reported. Furthermore, it is also possible to integrate the electrode and electrolyte in one step by simultaneous co-sintering. Based on this ultrafast co-sintering technique, an all-solid-state lithium-metal battery with a high areal capacity is successfully achieved, realizing a promising electrochemical performance at room temperature. This method can extend to other various ceramic multilayer-based solid devices.
烧结陶瓷电解质通常需要较长的处理时间和高温，这会导致挥发性元素损失和成本高昂。在此，报道了一种微波诱导碳热冲击的超快烧结方法，可在几秒钟内制备各种陶瓷电解质。此外，通过同时共烧结还可以一步将电极和电解质集成在一起。基于这种超快共烧结技术，成功制备了具有高面积容量的全固态锂金属电池，在室温下实现了有前景的电化学性能。该方法可扩展到其他各种基于陶瓷多层的固体器件。
