Invention Reference Number
Researchers at Oak Ridge National Laboratory and Pennsylvania State University have developed a novel semi-solid-state composite electrolyte for lithium metal batteries. Designed to address the challenges of low conductivity and poor dendrite resistance in conventional polymer electrolytes, this composite offers improved ion transport and interfacial stability. The innovation enhances battery safety, performance, and cycling life, supporting next-generation energy storage systems for electric vehicles and other high-performance applications.
Description
This technology introduces a polymer–ceramic composite electrolyte engineered to overcome the limitations of existing lithium battery electrolytes. The composite integrates a uniquely structured polymeric host with specially formulated high-entropy ceramic fillers to create a stable semi-solid-state system. This configuration enables superior ionic conductivity at ambient conditions. The material’s tailored chemical interactions and rheological balance enhance its compatibility with lithium metal anodes, effectively mitigating dendrite formation and extending cycle life under demanding operating temperatures. By combining the mechanical robustness of a solid electrolyte with the flexibility of a polymer matrix, this innovation provides a safer and more efficient alternative for high-energy lithium-based batteries.
