Li_2.9Fe_0.9Zr_0.1Cl₆ as Redox-Active Catholyte for Solid-State Li-Ion Batteries.

ABSTRACT: Solid electrolytes are one of the key challenges that hinder the commercialization of all-solid-state batteries. Most efforts have been made to advance the development of solid electrolytes as separators, while the development of catholytes, particularly redox-active catholytes, has been less extensively studied. The high loading of catholytes in composite cathodes, while facilitating ionic conduction, drastically decreases the energy density of the battery. Here, we report an alternative strategy to improve the energy density by using Li_2.9Fe_0.9Zr_0.1Cl₆ as a redox-active catholyte. With a composite cathode containing uncoated LiCoO₂ and Li_2.9Fe_0.9Zr_0.1Cl₆, the solid-state cell not only shows
