摘要: Abstract To warrant long-term reliability for application of electrolytes in solid state batteries also mechanical properties have to be considered. Current work concentrates on Li1+xAlxTi2-x(PO4)3 (LATP), which based its conductivity is a very promising material. Effect sintering temperature (950, 1000, 1050, 1100 °C) and was tested. Impedance tests were carried out as main focus the behavior LATP samples determined. The impedance results revealed that sintered at 1100 °C had highest ion conductivity. elastic modulus hardness, appeared related mainly smaller lattice parameter with additional effects lower porosity especially when tested higher loads. indicate enhancement both requires lowering secondary phase content densifying microstructure
