A cost-effective, ionically conductive and compressible oxychloride solid-state electrolyte for stable all-solid-state lithium-based batteries.

ABSTRACT: To enable the development of all-solid-state batteries, an inorganic solid-state electrolyte should demonstrate high ionic conductivity (i.e., > 1 mS cm^-1 at 25 °C), compressibility (e.g., > 90% density under 250-350 MPa), and cost-effectiveness (e.g., < $50/kg). Here we report the development and preparation of Li_1.75ZrCl_4.75O_0.5 oxychloride solid-state electrolyte that demonstrates an ionic conductivity of 2.42 mS cm^-1 at 25 °C, a compressibility enabling 94.2% density under 300 MPa and an estimated raw materials cost of $11.60/kg. As proof of concept, the Li_1.75ZrCl_4.75O_0.5 is tested in combination with a LiNi_0.8Mn_0.1Co_0.1O₂-based positive electrode and a L
