Abstract: Abstract The present invention discloses a highly homogeneous hybrid ceramic–polymer composite electrolyte for solid-state lithium batteries. The composite electrolyte comprises a multi-component matrix consisting of an organic polymer matrix (40–70 wt%), a highly dissociable lithium conductive salt (10–25 wt%), and nano-sized inorganic ceramic filler particles (10–40 wt%) that are uniformly dispersed within the polymer structure. The ceramic nanoparticles are optionally treated with a surface modification agent, such as graphene or a silane coupling agent, to eliminate particle agglomeration and enhance phase compatibility. The resulting integrated configuration establishes continuous, three-dimensional lithium-ion transport pathways that provide an exceptional room-temperature ionic conductivity greater than 10^{-4} S/cm, while simultaneously enhancing mechanical shear modulus to suppress lithium dendrite penetration and ensuring thermal stability up to 300°C. A low-temperature, roll-to-roll compatible solution-casting and hot-pressing fabrication methodology is also disclosed. The invention is ideally suited for high- safety, high-energy-density applications in electric vehicles, aerospace systems, and grid energy storage.
