Sodium-ion batteries are a promising candidate to replace lithium-ion batteries for large-scale energy storage system because of their cost and safety benefits.
ORNL researchers have developed a new method for producing thermoset foam insulation with improved processing and installation outcomes.
Knowing the state of charge of lithium-ion batteries, used to power applications from electric vehicles to medical diagnostic equipment, is critical for long-term battery operation.
The proposed solid electrolyte can solve the problem of manufacturing solid electrolyte when heating and densifying the solid electrolyte powder. The material can avoid also the use of solid electrolyte additive with cathode to prepare a catholyte.
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.
Important of the application is enabling a cost-effective precision manufacturing method Current technology is limited to injection molded individual pi-joints limiting control of pi-joint direction, this creates hurdle in introducing high volume production to the composite in
