We report novel calcium-substituted perovskite-type solid state electrolyte with nominal composition Li0.344Sr0.433Ca0.02Ta3/4Hf1/4O3, which we compare with Li3/8Sr7/16Ta3/4Hf1/4O3. The compounds were synthesized via solid-state reaction and studied by X-ray and neutron powder diffraction and electrochemical impedance spectroscopy. Neutron powder diffraction allowed the Li position in the structure to be accurately determined. Calcium-substituted phase showed higher Li-ion conductivity than the analogous calcium-free phase obtained with our synthesis method. High total Li-ion conductivities of...

Researchers can now work toward finding a solution.

Contemporary Amperex Technology Co. Limited plans to begin production of the battery in the near future.

Using computer simulations and X-ray experiments, researchers could “see” in detail why lithium ions move slowly in a solid-state battery—specifically, at the electrolyte-electrode interface. The work could lead to new strategies to enhance ionic conductivity in solid-state batteries.
