This work report a circa. 10-time improved σ_g.b for LATP by adding Sm₂O₃ as sintering additives. The average- and microstructure of the samples are investigated to understand the origin of the conductivity enhancement. The finding highlights microstructural tuning by sintering additives as a novel conductivity enhancement method for LATP.
