Reaction of LiAlTi(PO) and LiNiCoMnO in Co-Sintered Composite Cathodes for Solid-State Batteries.

All solid-state batteries offer the possibility of increased safety at potentially higher energy densities compared to conventional lithium-ion batteries. In an all-ceramic oxide battery, the composite cathode consists of at least one ion-conducting solid electrolyte and an active material, which are typically densified by sintering. In this study, the reaction of the solid electrolyte LiAlTi(PO) (LATP) and the active material LiNiCoMnO (NCM622) is investigated by cosintering at temperatures between 550 and 650 °C.
