A cost-effective and humidity-tolerant chloride solid electrolyte for lithium batteries.

ABSTRACT: Li-ion-conducting chloride solid electrolytes receive considerable attention due to their physicochemical characteristics such as high ionic conductivity, deformability and oxidative stability. However, the raw materials are expensive, and large-scale use of this class of inorganic superionic conductors seems unlikely. Here, a cost-effective chloride solid electrolyte, Li₂ZrCl₆, is reported. Its raw materials are several orders of magnitude cheaper than those for the state-of-the-art chloride solid electrolytes, but high ionic conductivity (0.81 mS cm^-1 at room temperature), deformability, and compatibility with 4V-class cathodes are still simultaneously achieved in Li₂ZrCl₆. Moreover, Li₂ZrCl₆ demonstrates a humi
