Solid Lithium Ion Conducting Electrolytes Suitable for Manufacturing Processes

Oak Ridge National Laboratory

Contact ORNL About This Technology


Technology Marketing SummaryThe lithium ion battery found in electronics like cell phones uses liquid electrolytes associated with shorter battery life; this material is also a safety hazard if it is overheated or overcharged. Batteries with solid lithium ion conducting electrolytes would overcome these limitations, but they have insufficient power to meet device energy requirements at a reasonable cost. Researchers at ORNL invented a method for synthesizing materials from solid state reactions that resolves some of these problems and improves battery performance. DescriptionThis method provides control of particle size, shape, and surface area of the lithium ion–conducting solid oxide material. The material’s nanosized particles improve battery performance. While other researchers have synthesized a variety of materials from solid state reactions, those methods cannot control particle properties and are not applicable to an assembly line manufacturing process.

The invention is cost-effective and suitable for manufacturing solid electrolyte materials for batteries as thin films and powder. The researchers are continuing to characterize the improved nanostructures.
