  • Patent number: 11955595
    Abstract: A ceramic-polymer film includes a polymer matrix; a plasticizer; a lithium salt; and AlxLi7-xLa3Zr1.75Ta0.25O12 where x ranges from 0.01 to 1 (LLZO), wherein the LLZO are nanoparticles with diameters that range from 20 to 2000 nm and wherein the film has an ionic conductivity of greater than 1×10?3 S/cm at room temperature. The nanocomposite film can be formed on a substrate and the concentration of LLZO nanoparticles decreases in the direction of the substrate to form a concentration gradient over the thickness of the film. The film can be employed as a non-flammable, solid-state electrolyte for lithium electrochemical cells and batteries. The LLZO serves as a barrier to dendrite growth.
