ORNL researchers achieved the highest wireless power transfer level for a light-duty passenger vehicle when the team demonstrated a 100-kW wireless power transfer to an EV using ORNL’s patented polyphase electromagnetic coupling coil.

Novel technology reaches 100-kW wireless power transfer for passenger vehicle

A team of ORNL researchers demonstrated that a light-duty passenger electric vehicle can be wirelessly charged at 100-kW with 96% efficiency using polyphase electromagnetic coupling coils with rotating magnetic fields. ORNL’s patented system transferred power to a Hyundai Kona EV across a five-inch airgap using electromagnetic fields, a process similar to the wireless charging of small consumer devices.

Low-Cost Hot Melt Adhesives with Improved Adhesive Strength
202305428 // Manufacturing
Adhesives for metal parts typically are liquid-based which require complex processing. This technology is a hot melt adhesive that is mixed and applied in a solid form and after the heating and cooling cycle creates strong bonds with the substrates in a matter of seconds. These adhesives show excellent adhesion on the metal surface such as steel while they can be readily removed on demand. These adhesives can also adhere to aluminum, wood, and paper.

Chemical Upcycling of Poly(ethylene Terephthalate) Waste into Alpha-Omega-Dialkene Compounds
202305430 // Chemicals // Materials
Most plastic is discarded after a single use, with about 76% of plastic waste discarded into landfills annually. The current practice is wasting feedstock resources, energy, and carbon used for their production. This technology is a new and unique way to upcycle thermoplastic polyesters, specifically poly(ethylene terephthalate), breaking it down and converting it using chemical means into added value organic compounds that can be used as plasticizers, organic building blocks, or monomers for polymer synthesis. This upcycling process can help combat accumulation of plastic waste in the environment and help advance toward a net-zero carbon society. 

Substrate Exchange Turret with Laser Heating for Physical Vapor Deposition Platforms
202305442 // Materials
The substrate exchange turret with laser heating is a device that allows for up to ten substrates to be mounted into a physical vapor deposition (PVD) chamber at one time and be heated with a laser for temperature control during film growth. The turret rotates one of the ten substrates in line with the laser heater for thin film deposition while shielding the other nine. This device allows for artificial intelligence and machine learning algorithms to conduct ten successive thin film growth experiments without human intervention, enables autonomous thin film growth with PVD processes.

Method to Generate Temperature Inversion within a Porous Preform using Microwave for CVI Synthesis
202305443 // Manufacturing
Ceramic matrix composites are used in several industries, such as aerospace, for lightweight, high quality and high strength materials. But producing them is time consuming and often low quality. It usually takes 600 to 2,000 hours to produce using traditional methods, and the materials are difficult to manufacture. This technology utilizes microwaves for inverted heating of preform ceramic composites to reduce manufacture time but increase efficiency and quality and lower costs.

Novel Additively Manufactured Nb-Si-Cr-(Mo) Refractory Alloys with High Strength and Oxidation Resistance
202305447 // Transportation
High strength, oxidation resistant refractory alloys are difficult to fabricate for commercial use in extreme environments. A niobium-based alloy is the most widely commercially used refractory alloy as it can withstand high temperatures, large temperature gradients, and hypersonic speeds that cause high stress on materials. However, its low strength and poor oxidation resistance have limited its use. This technology utilizes additive manufacturing to fabricate improved and novel refractory alloys of high strength and oxidation resistance for extreme environments that overcome these obstacles.
