Volkswagen Group of America, Inc. (VWGoA) is boosting its automotive research in the United States to further accelerate electric mobility and sustainable transportation innovation. The company continues to center strategic areas of research in dedicated technology units across the country, as well as foster co-innovation with universities and federal research facilities. One key unit is located in Tennessee: Volkswagen’s Innovation Hub in Knoxville is driving applied materials science in collaboration with the University of Tennessee (UT) and Oakridge National Lab (ORNL). There, integrated teams are pushing breakthroughs in automotive lightweight composites, recyclable interior materials, and EV wireless charging.

“We are accelerating innovation within electric vehicles and contributing to more sustainable transportation in America by focusing our efforts on some of the most transformative automotive research being done in the country,” said Pablo Di Si, President and CEO at Volkswagen Group of America Inc. “Our technology teams in Tennessee are a great example. There, we are tapping American ingenuity fostered by the unique blend of world-class academic research and Volkswagen’s leading industry capabilities.”

Opened in 2020, Volkswagen’s Innovation Hub is located at the University of Tennessee Research Park at Cherokee Farm in Knoxville, in a region referred to as ‘the Materials Valley’ due to the concentration of research facilities. This includes the ORNL, of which VWGoA has also established research collaborations. Volkswagen researchers, UT faculty and doctoral students as well as ORNL scientists collectively drive research and co-innovation of applied materials research.

“Centering more knowledge in the United States is part of Volkswagen’s strategy for growth and is vital for sourcing and developing talent,” Di Si added.

“The Volkswagen Innovation Hub is a powerful example of the kind of scientific advances and industry-ready technology that you can bring to market when you locate scientists and researchers from across disciplines and organizations together in one place.”, said UT Chancellor Donde Plowman. “With partners like Volkswagen, Oak Ridge National Lab, and others industry leaders and tech startups located at UT’s Research Park, we have created a thriving innovation ecosystem.”

Volkswagen researchers are working on new material structures to reduce vehicle weight, which helps to increase the range of electric vehicles (EVs). As a first pilot, the team has chosen the steel frame that houses the EV battery pack in the vehicle and shields it from physical impacts.

By running a deep learning algorithm (simplified: artificial intelligence) with up to millions of parameters on UT’s high performance compute cluster, the team has developed a modular repeating structure in shapes of tiny pyramids. This structure can be 3D-printed from liquid resins and holds 30,000 times its own 0.15lbs-weight (68g). A newly created frame would be up to 60 percent lighter. Hardcore durability tests showed that it exceeds the conventional steel frame in energy absorption, and could serve as a lightweight, yet ultra-robust alternative.

The hub team at UT’s Center for Renewable Carbon is developing recyclable alternatives to plastic parts and foils in the vehicle interior. Their focus: paper. The team has patented a method of preforming and hot-pressing cellulose fiber reinforced thermoplastics into the durable interior parts customers expect.

These paper-based composites are not only recyclable, they can also be transformed into various interior shapes and sizes, including backlit and ambient light options. The team has also innovated ways to add different textures and colors, so vehicle interior designers enjoy flexibility and creative freedom.

The Volkswagen brand is already checking opportunities to include these paper-based interior parts in future model lines and work to support industry-scale production.

The Volkswagen team kicked off lightweight materials research with UT by recreating the lift gate of a MY2020 Volkswagen Atlas using sheet molding compound (SMC), a type of fiberglass reinforced plastic. The new lift gate proved to be 13 pounds lighter than the conventional metal-based version; a weight-savings of more than 35 percent, which could help to increase the range of electric vehicles and those powered with a combustion engine. In addition, the alternative composite lift gate does not need changes in assembly sequence compared to conventional versions – meaning those components are fit for high volumes.

The team’s research breakthrough has already found its way into vehicle production. Bentley and Lamborghini have adopted these new materials and the molding process for the Bentley Continental, and in the Lamborghini Aventador. The team in Knoxville has also started a research project to explore lightweight options for pickup beds and rugged components.

More recently, Volkswagen and UT researchers have further refined molding processes and ways to optimize durability, quality and design options. One specific take is to optimize the fiber-matrix-interface, a process called “sizing” – essentially creating the smoothest, most durable coat for fibers possible.

Volkswagen’s team has patented a unique coil and charging pad design with silicon-carbide materials to optimize charging speed and safety. Their goal: Help make charging an electric vehicle as easy and comfortable as pulling into a normal garage spot.

In the first early trials with a silicon-carbide inverter, this prototype system has shown high efficiency. Using Volkswagen’s expertise in vehicle power electronics, ORNL’s capabilities in high power wireless charging, and UT’s knowledge of power electronics optimization, the research team has been able to increase the charging power level up to 120 kW with this prototype from an earlier 6.6kW prototype, with a future goal of 300 kW.

Volkswagen’s Innovation Hub Knoxville is contributing to the global Volkswagen Group’s larger innovation ecosystem, including innovation centers in Belmont, California; Wolfsburg, Germany; and Beijing, along with hubs in Singapore, Tel Aviv and Tokyo.

Nikola,and Fortescue Future Industries (FFI), a global green energy and metals company committed to leading the world in stepping beyond fossil fuels by developing green electrons, green hydrogen and green technology at scale, announced FFI will acquire Nikola’s Phoenix Hydrogen Hub (PHH) project.

Nuvola Technology (formerly Millibatt), a venture-funded battery materials start-up, announces its patented SafeCoat Direct Deposition Separator (DDS)™ material that eliminates the primary cause of lithium-ion battery fires. SafeCoat replaces the troublesome plastic sheet separator material used in today’s battery manufacturing process. Its ingenious spray-on coating fully encapsulates and protects the battery’s electrodes from a thermal runaway and a potential fire. Nuvola was selected as one of ten winners in LG Energy Solution’s annual 2022 Battery Challenge, competing with over 100 companies. The LG Battery Challenge competition is designed to accelerate the adoption of new battery technologies and business models.

The primary cause of battery fires is a manufacturing error internal to the battery cells of today’s electric vehicles (EVs), e-scooters, e-bikes, and cell phones. These batteries can contain thousands of tissue-paper thin folded sheets of a porous plastic membrane that keeps the internal battery electrodes from coming in contact. This 50-year-old sheet separator technology is prone to manufacturing assembly errors and failure. During the battery assembly process, a single sheet separator can become damaged, creating an undetectable wrinkle, misalignment, misfolding, or even a tiny tear allowing the electrodes to come in contact. This may cause a fire — days, months, or years later. SafeCoat solves this safety issue by replacing the sheet separator with a sprayed polymer electrode coating that ensures the electrodes never come into contact.

“Improving battery safety is one of the highest priorities for the EV market, with large, energy dense batteries representing a significant threat to public safety in the event of a fire,” said James Hodgson, Research Director, Automotive at ABI Research. “Nuvola Technology’s approach of separator coating offers the opportunity to improve both safety and production yield by modifying one step of the manufacturing process.”

The recent EV and e-bike fires are examples of this insidious and tragic battery failure that SafeCoat can eliminate. The Nuvola SafeCoat product is now under evaluation by several major battery and car manufacturers, with products utilizing the technology expected in the market in 2025.

Nuvola has a growing patent portfolio spanning several new battery materials for high-energy and microbattery applications. Its founders, Dr. Janet Hur and Dr. Leland Smith performed innovative battery material development while doing post-doctoral research at UCLA.

Starting in 2025, Nissan will begin offering EVs for the U.S. and Canadian markets with a NACS port. This will make charging on the Tesla Supercharger network seamless and convenient for drivers, significantly increasing the number of public fast-charging locations at which Nissan EVs can be charged1.

“Adopting the NACS standard underlines Nissan’s commitment to making electric mobility even more accessible as we follow our Ambition 2030 long-term vision of greater electrification,” said Jérémie Papin, chairperson, Nissan Americas. “We are happy to provide access to thousands more fast chargers for Nissan EV drivers, adding confidence and convenience when planning long-distance journeys.”

As part of Ambition 2030, Nissan is targeting more than 40% of its U.S. vehicle sales to be fully electric by 2030, with even more to be electrified. This includes two all-new, all-electric vehicles to be assembled2 at the Nissan plant in Canton, Mississippi, beginning in late 2025.ore details on the rollout of Nissan’s NACS compatibility will be communicated at a later date.
