ORNL has developed a new hybrid membrane to improve electrochemical stability in next-generation sodium metal anodes.
Direct air capture (DAC) technologies that extract carbon dioxide directly from the atmosphere are critical for mitigating effects of climate change.
The invention addresses the long-standing challenge of inorganic phase change materials use in buildings envelope and other applications by encapsulating them in a secondary sheath.
The technologies described herein provides for the High Temperature Carbonization (HTC) in the manufacturing of carbon fibers (CF). The conventional method for HTC is based in thermal radiation and this technology uses in a liquid medium.
Anisotropic bonded critical rare earth free permanent magnets in a polymer matrix fabricated using an additive manufacturing process.
Free-standing, thin films were fabricated with a binder resulting in nearly an order of magnitude thickness decrease while increasing porosity and activation energy. These effects of such diminished significantly. Free-standing films could be fabricated with a binder.
This technology creates a light and metalless current collector for battery application. Cathodes coated on this new current collector demonstrated similar contact resistance, lower charge transfer resistance and similar or high rate performance.
