Reaction Suppression Between a High-Ni Cathode Material (NMC622) and Li₇La₃Zr₂O₁₂ on Co-Sintering for Manufacturing Bulk-Type All-Solid-State Batteries: A New Method and Its Mechanism.

ABSTRACT: Co-sintering cathode materials with Li₇La₃Zr₂O₁₂ (LLZ) is a promising strategy for fabricating bulk-type all-solid-state batteries (ASSBs). However, preventing reactions between different materials, which is difficult with high-capacity cathode materials such as LiNi_0.6Mn_0.2Co_0.2O₂ (NMC622), is a pre-requisite for applying this strategy. To overcome this issue, Li_{1+ x}Ni_0.6Mn_0.2Co_0.2O₂ (x = 0.01-0.2), which intentionally deviates from the stoichiometric NMC622 composition, is synthesized here. The formation of impurity phases in the co-sintering process can be controlled by adjusting the co-sintering temperature and x. Impurity phases are
