Li₃TiCl₆ as ionic conductive and compressible positive electrode active material for all-solid-state lithium-based batteries.

ABSTRACT: The development of energy-dense all-solid-state Li-based batteries requires positive electrode active materials that are ionic conductive and compressible at room temperature. Indeed, these material properties could contribute to a sensible reduction of the amount of the solid-state electrolyte in the composite electrode, thus, enabling higher mass loading of active materials. Here, we propose the synthesis and use of lithium titanium chloride (Li₃TiCl₆) as room-temperature ionic conductive (i.e., 1.04 mS cm^-1 at 25 °C) and compressible active materials for all-solid-state Li-based batteries. When a composite positive electrode comprising 95 wt.% of Li₃TiCl₆ is tested in combination with a Li-In alloy negative electrode and Li₆
