TECHNOLOGY TRANSFER OPPORTUNITY: Carbon Fiber Sleeve Tempers Battery Thermal Runaway (MSC-TOPS-119)

NASA's Technology Transfer Program is seeking companies interested in obtaining license rights to commercialize, manufacture, and market a carbon fiber reinforced polymer (CFRP) sleeve technology that can prevent cell-to-cell propagation of thermal runaway events in lithium-ion battery cells. The technology has a technology readiness level (TRL) of 6 and is available for patent licensing. The CFRP sleeve provides multiple advantages over previous containment designs, including increased hazard safety, lower mass, reduced cost, lack of conductivity, and manufacture with readily available materials. Key features of the technology include: • Increased hazard safety • Lower mass • Reduced cost • Lack of conductivity • Manufacture with readily available materials • Compatibility with 18650 battery cells, which are widely used in commercially available products such as power tools, laptops, cameras, e-bikes, and electric cars.
