Enhancing Adoption of Sustainable Product Innovations: Addressing Reduced Performance with Risk-Reducing Product Modifications

Abstract Past studies have shown that the probability of the successful diffusion of sustainable product innovations is strikingly low. A potentially promising marketing strategy to reduce negative consumer perceptions of sustainable product innovations is risk-reducing product modifications (RPMs), which account…

Processes, models and the influencing factors for enhanced boiling heat transfer in porous structures

Abstract Due to the increasing volume of electric vehicles in automotive markets and the limited lifetime of onboard lithium-ion batteries, the large-scale retirement of batteries is imminent. The battery packs retired from electric vehicles still own 70%–80% of the initial capacity, thus having…

Confidence-aware reinforcement learning for energy management of electrified vehicles

Abstract The reliability of data-driven techniques, such as deep reinforcement learning (DRL) frequently diminishes in scenarios beyond their training environments. Despite DRL-based energy management strategies (EMS) having gained great popularity in optimizing the energy economy of electrified vehicles (EVs), their performance degradation in untrained…

X-rays Reveal Elusive Chemistry for Better EV Batteries

A team of scientists led by chemists at the U.S. Department of Energy’s Brookhaven National Laboratory and Pacific Northwest National Laboratory has unraveled the complex chemical mechanisms of a battery component that is crucial for boosting energy density: the interphase.

Taking Freight Trucks Electric Would Have Big Economic and Environmental Benefits for India

Diesel-fueled freight trucks play an outsized role in producing India’s total greenhouse gas and air pollution emissions. While the country has promoted policies to transition to electric vehicles for public transportation buses and cars, batteries that can power such large trucks have been too heavy and expensive to make their electrification possible. A new study shows that advances in battery technology and dramatically decreased battery costs in recent years have changed that. With the right policies and incentives, battery electric trucks would be more affordable to operate than diesel, and India could become a world leader in producing electric vehicles.

The Race is On: Nevada is in the Driver’s Seat for Burgeoning Lithium Industry. UNLV economic geologist talks lithium battery supply chain, green energy, and self-sustainability

The ‘Lithium-Ion Battery State’ may not have the same ring to it as ‘Battle-Born’ or ‘Silver State,’ but the reality is that Nevada could soon be a leader in the lithium battery supply chain – potentially giving the U.S. an edge in the arms race for the in-demand metal that’s the key to powering everything from your cell phone to electric vehicles.

Scientists Discover New Approach to Stabilize Cathode Materials

UPTON, NY—A team of researchers led by chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery performance. The findings, published in Nature Communications, demonstrated that the valence gradient can serve as a new approach for stabilizing the structure of high-nickel-content cathodes against degradation and safety issues.

Electric vehicles no environmental savior, could cause power grid problems

As Ford unveils its electric F150, West Virginia University experts note the shift from gasoline-powered engines is not an environmental panacea in the short term, but instead will mean significant and costly upgrades to the nation’s infrastructure. Citing recent events,…

Mapping Performance Variations to See How Lithium-Metal Batteries Fail

Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles: electrolyte depletion.

Commercial Truck Electrification is Within Reach

Researchers from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Los Angeles published a new study that makes the case for prioritizing public policy to help move long-haul trucking from diesel to electric. Doing so will mean huge gains in addressing the climate crisis and avoiding premature deaths due to local vehicular pollution, which disproportionately affects communities of color.

Chemists Settle Battery Debate, Propel Research Forward

UPTON, NY—A team of researchers led by chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has identified new details of the reaction mechanism that takes place in batteries with lithium metal anodes. The findings, published today in Nature Nanotechnology, are a major step towards developing smaller, lighter, and less expensive batteries for electric vehicles.
