Public-private alliance Li-Bridge, representing the US battery ecosystem, has released an action plan to accelerate creation of a robust domestic manufacturing base and supply chain for lithium-based batteries. The alliance was convened by the DOE and is managed by Argonne National Laboratory. The report’s 26 recommendations include a buying consortium for raw energy materials, a… Read more »

Argonne National Lab: Lithium-sulfur batteries are one step closer to realization
Scientists at the DOE’s Argonne National Laboratory are researching solutions to the drawbacks of lithium-ion batteries by testing alternate materials such as sulfur. Sulfur, says Argonne, is highly cost-effective, and lithium-sulfur batteries can hold more energy than ion-based ones. In a recent study, researchers created a layer in the battery that increases energy storage capacity… Read more »
Solenoid fundamentals: magnetic latching solenoids for EVs
Sponsored by TLX Technologies. One of the most challenging parts of new product realization is identifying optimal technology from the onset of a system concept. With the rapid development of the next generation of mobility technology in the form of vehicle electrification, alternative fuels such as hydrogen fuel cell technology, and the overall drive for… Read more »
Hyundai fuel cell trucks won’t be using green hydrogen after all
Governments around the world are dedicating taxpayer money to hydrogen projects, and these are invariably presented as using green hydrogen (produced by electrolysis using renewable energy). Hydrogen detractors often warn that, once these projects are funded, green hydrogen, which isn’t yet available at any scale, will prove impractical, and boosters will quietly switch to grey… Read more »
Don’t just delay cell-to-cell thermal propagation, stop it.
Sponsored by Aspen Aerogels Battery engineers face the daunting challenge of maximizing thermal runaway protection while optimizing vehicle performance. This task becomes even more critical as cell-to-pack and cell-to-chassis designs increase in popularity because manufacturers lose the added protection that can be built into a module-based design. Although newer chemistries such as LFP and solid-state… Read more »
Power electronics thermal limits and how to not exceed them
To someone who isn’t involved in power electronics design, it might seem unreal that the amount of power a component can handle depends more on how effectively waste heat can be removed from it than it does on the specific electrical ratings. Sure, the voltage and current ratings are important (especially the voltage rating), but… Read more »

2022 Lucid Air: The makers of the first 500-mile EV should be taken seriously
Created by engineers with years of EV experience, the 2022 Lucid Air is a stunning debut that confronts Tesla—and Mercedes-Benz—with a new competitor. It’s been a long time coming, but the 2022 Lucid Air has been worth the wait. The new carmaker’s all-electric luxury sedan not only competes directly with the aging Tesla Model S,… Read more »

2022 Rivian R1T: A real pickup truck makes an impressive debut
Could Rivian emerge as “the next Tesla?” On the strength of its debut truck, that’s not an unreasonable question. If you want to attract attention, keeping a company in stealth mode for several years is a good way to do it. The startup carmaker Rivian was founded a decade ago by RJ Scaringe, but it… Read more »
