Battery Technologies
Blended Electrolyte Additives Improve Stability of Earth-Abundant Battery Cathodes
NREL and Argonne National Lab used advanced electron microscopy to uncover key nanoscale mechanisms, guiding new electrolyte approaches that enable earth-abundant alternatives for battery cathodes instead of expensive, toxic, and supply-limited cobalt.
Automated Machine-Learning Pipeline Advances Silicon Battery Lifetime Predictions
To manage the continued uptake of new validation data that will enable informed decision-making on cell calendar life, the NREL-led Silicon Consortium Project developed an automated pipeline for processing battery lifetime predictions, uncertainty quantification, and outlier flagging.

Electrification Technologies
Accelerated Aging Station Will Demonstrate How To Build a Better Commercial Powertrain
NREL designed an accelerated aging station, informing safer, more durable, and more reliable commercial vehicle designs. The station enables researchers to discover how and why power modules and converters degrade in electrified medium- and heavy-duty vehicles, using a powertrain digital twin built in partnership with Oak Ridge National Lab and Sandia National Labs.

Off-Road, Rail, Marine, and Aviation Technologies
Group Contribution Method Solidifies Accuracy of Fuel Property Prediction Models for Jet Fuels
NREL incorporated the group contribution method, a way to predict jet fuel thermophysical and combustion properties, into FuelLib—an open-source Python tool for calculating individual compound and fuel mixture properties. The method reduces both costs and time, requiring only a small volume of the prototype fuel for validation that produces results within hours.

Materials Technology
NREL Determines Hybrid Composites of Multiple Fiber Types Can Maintain Performance and Lower Costs by up to 95%
To address the barriers carbon-fiber-reinforced composites face for adoption by the automotive industry, NREL designed hybrid composites of multiple fibers that retain a material's strength at a lower cost and provide ductility. Recent analysis shows the material cost can be less than $2 per kilogram of mass saved, while also lowering energy intensity.

Technology Integration
Collaboration Enhances Understanding of Strategies and Resource Needs To Help First Responders Safely Address Electric Vehicle Incidents
Comprehensive training to provide safety training to emergency responders is largely lacking or conflicting across the United States. NREL collaborated with a Clean Cities and Communities coalition to identify strategies and resources to help emergency responders safely address incidents involving electric vehicles (EVs) under a variety of scenarios and conditions.
NREL Athena Researchers Develop Models To Inform Critical Airport Infrastructure Planning
U.S. airports are increasingly busy with more passengers and flights but must also balance growing demands on key energy infrastructure and manage costs. To help airports increase operational efficiencies and gain insights for infrastructure and grid planning, the NREL-led Athena team developed a suite of models that considers electrification solutions to be integrated into the web-based Aeroportal platform.

Analysis
Research Team Lays Groundwork for a National Medium- and Heavy-Duty Vehicle Charging Needs Assessment
NREL developed an initial modeling approach and set of assumptions to estimate nationwide medium- and heavy-duty EV charging needs, helping planners and developers make informed decisions and avoid unnecessary costly investments. Infrastructure quantities, capital costs, and power requirements broken down by location type and charging type will be included in results.

Energy Efficient Mobility Systems
Integrating Thermal Effects Improves Accuracy of Energy Predictions in RouteE Powertrain
NREL integrated temperature sensitivity into the RouteE: Route Energy Prediction Powertrain tool using large-scale thermal simulations from the FASTSim™: Future Automotive Systems Technology Simulator to more accurately predict how ambient temperatures affect battery-EV energy consumption and driving range. The improved models reduce prediction errors by nearly 50%, especially at extreme hot and cold temperatures.
Augmented Reality Application To Track Test Connected and Automated Vehicles Offers Simulated Validation Opportunities Ahead of Real-World Deployments
For a project with ARPA-E: Advanced Research Projects Agency – Energy, NREL collaborated with Leidos, the American Center for Mobility, and the Michigan Tech Research Institute to establish a framework to track test connected and automated vehicles in a simulated environment informed by real-world drive cycles. This work enables early-stage evaluation without the risk of public road testing and reduces costs by substituting simulated vehicles for real ones.
