The co-processing of cathode and composite electrolyte for solid state polymer batteries has been developed. A traditional uncalendared cathode of e.g.
ORNL has developed a new hybrid membrane to improve electrochemical stability in next-generation sodium metal anodes.
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.
This technology aims to provide and integrated and oxidation resistant cladding or coating onto carbon-based composites in seconds.
Electric vehicle drive fluids must have a high dielectric constant to avoid current leakage or even short circuits. On the other hand, lubricants should possess sufficient conductivity to allow static electricity to be released.
Ionic liquids comprising quaternary ammonium and phosphonium cations have been developed as eco-friendly lubricant additives. These additives are tailored for use in environmentally acceptable lubricants (EALs) like polyalkylene glycols, vegetable oils, and synthetic esters.
