Even as it insists that Europe should be a leader in electromobility, Volkswagen is collaborating with oil giant Shell to argue that EU planners should rely heavily on biofuels to meet proposed emissions targets. Executives from the two industrial giants recently released a study that proposes greater use of biofuels as an alternative to increasing… Read more »

Snail shells inspire new battery design
Nanostructured electrodes in Li-ion batteries have several advantages, including shorter distances for charge-carrying particles to travel and a high surface area that provides more active sites for electrochemical reactions to occur. However, working with nanoscale materials is tricky – due to their tiny size, they can be hard to control and hold in place. To… Read more »
Operando X-ray tomography reveals silicon-electrolyte interface dynamics in solid-state batteries
Silicon anodes can greatly boost the energy density of all-solid-state batteries, but their large volume changes often cause contact loss with solid electrolytes. Si can store more lithium than graphite, but its volume can expand by as much as 410% during charging, generating mechanical stress that cracks particles and weakens their contact with the solid… Read more »
Inside the EV battery recall process—the complexity of safety and logistics
As EV adoption accelerates, so does the frequency of battery recalls—and the operational expertise they require. In recent months, a string of recalls from major automakers has underscored the complexities of EV battery systems. Hyundai recently pulled back a limited number of 2025 IONIQ 5s in the US after identifying a short-circuit risk linked to… Read more »
DHL to electrify 66% of its vehicle fleet by 2030
Global logistics and shipping firm DHL has announced plans to accelerate the electrification of its vehicle fleet. DHL currently operates some 39,000 EVs in pickup and delivery services, representing more than 41% of its fleet. The company plans to raise that proportion to 66% by 2030. New electric trucks and light commercial vehicles are to… Read more »
Potting vs. foam: the battery pack safety advantage
Sponsored by Epic Resins. As the e-mobility industry continues to revolutionize the way we use EVs and LEVs, one critical question persists for engineers: How can we design a safer battery pack? A recent conversation between Joe Staller, R&D Chemist at Epic Resins, and Luke Workman, Chief Scientist at Electric Goddess, revealed eye-opening insights into material… Read more »
Letter from Switzerland: EVs are taking over the Alps
Switzerland has long seemed a bit of an outlier among the electrifying nations of Europe. I’ve seen EVs on Swiss roads since I first visited the country in the early 1990s, and I’ve seen their numbers grow in my frequent travels in the country, but in recent years, adoption of modern EVs has been modest… Read more »
Ford Charge network launches with fast charging stations at 320 Ford dealerships nationwide
Ford has launched Ford Charge, a new network of nearly 1,200 DC fast chargers located at over 320 Ford dealerships across the United States. Ford says the network provides reliable public charging for all compatible electric vehicles, not just Ford models. John Grappone Ford in Bow, New Hampshire, reports it is the first dealership to… Read more »
Korean scientists find a way to control concentration gradients in high-nickel cathodes
Researchers at Pusan National University in South Korea have introduced a novel mathematical framework for lithium-ion batteries containing high-nickel cathodes that enables flexible full concentration gradient (FCG) or core-shell designs. In a new study, an international research team led by Associate Professor Hyun Deog Yoo from the Department of Chemistry and the Institute for Future… Read more »
Wacker announces extrudable silicone for EV busbar insulation with fire-resistant ceramic layer
Wacker has announced a new extrudable silicone rubber designed to insulate busbars in high-voltage traction batteries for electric vehicles. The new material, ELASTOSIL R 531/60, addresses increased electrical and thermal demands resulting from rising EV battery voltages, with nominal system voltages commonly ranging from 300 to 900 volts. The company says the material’s processability by… Read more »
