Abstract: High energy density and long cycle life all solid-state electrolyte lithium-ion batteries use ceramic-polymer composite anodes which include a polymer matrix with ceramic nanoparticles, silicon-based anode active materials, conducting agents, lithium salts and plasticizer distributed in the matrix. The silicon-based anode active material are anode active particles formed by high energy milling a mixture of silicon, graphite, and metallic and/or non-metallic oxides. A polymer coating is applied to the particles. The networking structure of the electrolyte establishes an effective lithium-ion transport pathway in the electrode and strengthens the contact between the electrode layer and solid-state electrolyte resulting in higher lithium-ion battery cell cycling stability and long battery life.

Abstract: Ceramic-polymer film includes a polymer matrix, plasticizers, a lithium salt, and a ceramic nanoparticle, LLZO: AlxLi7-xLa3Zr1.75Ta0.25O12 where x ranges from 0 to 0.85. The nanoparticles have diameters that range from 20 to 2000 nm and the film has an ionic conductivity of greater than 1×10?4 S/cm (?20° C. to 10° C.) and larger than 1×10?3 S/cm (?20° C.). Using a combination of selected plasticizers to tune the ionic transport temperature dependence enables the battery based on the ceramic-polymer film to be operable in a wide temperature window (?40° C. to 90° C.). Large size nanocomposite film (area ?8 cm×6 cm) 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. This large size film can be employed as a non-flammable, solid-state electrolyte for lithium electrochemical pouch cell and further assembled into battery packs.
