Chemical compatibility at the interface of garnet-type Ga-LLZO solid electrolyte and high-energy Li-rich layered oxide cathode for all-solid-state batteries.

ABSTRACT: All-solid-state batteries (ASSBs) with a garnet-type solid electrolyte have been considered promising alternatives to traditional batteries with a liquid organic electrolyte, due to their enhanced safety and ability to accommodate high energy density electrodes. In this study, we conducted a comprehensive investigation of the high-temperature chemical compatibility between the garnet-like Li_6.4Ga_0.2La₃Zr₂O₁₂ (Ga-LLZO) electrolyte and high-energy-density Li-rich layered Li_1.2Ni_0.2Mn_0.6O₂ cathode (LNM). Our findings suggest that a high temperature reaction between the Li-rich cathode and Ga-LLZO occurs at 700-900^oC depending on the form of reactants. This reaction results in the form
