Polycationic doping of the LATP ceramic electrolyte for Li-ion batteries.

ABSTRACT: All-solid-state Li-ion batteries (LIBs) with a solid electrolyte instead of a liquid one demonstrate significantly higher safety in contrast with the conventional liquid-based LIBs. An inorganic NASICON-type Li conductor Li_1.3Al_0.3Ti_1.7(PO₄)₃ (LATP) is a promising solid electrolyte with an ionic conductivity of up to 10^-3 S cm^-1 at room temperature. However, LATP gradually degrades in contact with Li metal because of reduction of Ti⁴⁺ to Ti³⁺, resulting in a lower ionic conductivity at the electrolyte-electrode interface. Cation doping is a promising approach to stabilize the LATP structure and mitigate the Ti reduction. Here, we report our findings on the alternative polycationic doping stra
