Mechanical Properties of Hot Isostatically Pressed Li0.35La0.55TiO3

The mechanical properties of polycrystalline Li0.35La0.55TiO3 (LLTO) are investigated after sintering followed by hot isostatic pressing (HIP). The elastic modulus (223 GPa), hardness (Knoop hardness 7.2 GPa), and flexure strength (252 MPa) values for HIP LLTO are in general higher than those for other solid Li-ion conductors thus, making it an excellent choice as a Li-ion conducting solid electrolyte based on mechanical properties.
