Higher energy density batteries and smaller, more powerful e-motors capable of ultra-fast charging create thermal management challenges for EV safety, longevity and efficiency.
One of the biggest challenges in designing batteries for plug-in hybrid (PV) and electric vehicles is thermal management of the battery pack. Battery components must operate in the optimum temperature window of 25°C during operations and below 60 ° C while charging.
Solutions like our BETAFORCE™ TC thermal conductive adhesives and BETATECH™ thermal interface materials s enable crash-durable assembly, enhanced thermal stability, and uniform thermal conductivity from the battery cells to the EV cooling system.
BETAFORCE™ TC an ideal choice for joining composites and other dissimilar materials in a variety of lightweight designs, including modular assemblies. It can be used to bond coated metals like steel to aluminum, carbon fiber panels to steel or aluminum, and sheet molding compound (SMC) to aluminum.
These features allow our automotive customers to design safe, durable, fast-charging batteries with a higher energy density, while lowering the cost of material input and production.
In addition to our adhesive solutions, our Zytel®, Zytel® PA, and Hytrel® materials have the resistance, stability, conductivity, and tolerance to compose the subsystems of fuel cell EVs.
We work with customers to help guide material selection, component testing, design and simulation to meet each customer’s unique challenges and objectives.
The Indian government plans to have India’s railways routes fully electrified by 2023 and fully powered by renewable sources by 2030. DuPont Kapton® FCRC wire insulation coupled with DuPont Nomex® slot liner insulation is the standard for high efficiency traction motor insulation systems for demanding, high temperature rail applications,
Photovoltaic panels are expected to convert sunlight into energy for 30 years or more, but solar panels in the field often experience degradation and other failures that shorten their useful life, thereby reducing their ability to produce renewable energy. Tedlar-based backsheets have been demonstrated to significantly extend panel lifespan, with multiple examples of installations generating electricity well beyond 30 years.
In August 2021, Hurricane Ida significantly impacted our Pontchartrain, LA manufacturing facility. Preparations for site operations, employee safety and community recovery began days ahead and continued weeks after.
Hydrofluorocarbons (HFC) are used in blowing agents and manufacturing of other building insulation materials. Some HFCs have high global warming potential (GWP) where they end up in the atmosphere and contribute to climate change.
Creating a water-optimized future relies on innovation and action now, and in future generations.
The “Flow of Life” project promotes water science literacy and education across primary and secondary students in China.
Many rivers around the world are now classified as “high stress”. This means that more than 40% of the naturally available water in the basin is removed leading to the risk of water scarcity. Our Zhangjiagang site in China set a sustainability goal to reduce wastewater generation, and address other water usage opportunities.
DuPont provides solutions that enable vehicle electrification and expansion of the electronic vehicle (EV) market, including thermal management, battery assembly, and enhanced connectivity
