About this technology
Overview
Innovators from the NASA Langley and NASA Glenn Research Centers have developed materials and processes to use carbon nanomaterials as bipolar membranes or plates for separating solid-state battery unit cells. Using carbon materials over current bipolar plates will be an enabling technology for lightweight, high energy density solid-state batteries. Bipolar membranes or plates provide a chemically inert but electrically conductive layer separating solid-state battery unit cells that allow them to be stacked within a single package. Here, the developed bipolar plate materials include films or membranes of graphene, holey graphene, and carbon nanotubes. These carbon materials provide a significant weight savings over currently used metallic materials while maintaining the necessary performance characteristics of the bipolar plates. These new bipolar membranes or plates may be employed in high energy density solid-state batteries for electrified aircraft, electric vehicles, or a variety of electric devices that require high performance batteries.
