UMD researchers create new architecture for solid-state Li metal batteries - Green Car Congress (blog)

Flexible lithium-ion conducting ceramic textile. The lithium-ion conducting ceramic textile is flexible and retained the physical characteristics of the original template. The unique textile structure enables long-range lithium-ion transport pathways via continuous fibers and yarns, high surface area/volume ratio of solid ion conductors and multi-level porosity distribution. Gong et al. Click to enlarge. The textile also provided an electrolyte framework when designing a 3D electrode to realize ultrahigh cathode loading (10.8 g/cm2 sulfur) for high-performance Li-metal batteries. The resulting battery delivered a high capacity of 1000 mAh/g. Characterization of garnet textile 3D electrode architecture for solid state Li-S batteries loaded with 10.8 mg/cm2 sulfur. (a) Photograph of a garnet textile sintered on the dense supporting electrolyte. (b) SEM image of the sulfur ca...
