The US Army Combat Capabilities Development Command (DEVCOM) has awarded a $550,000 joint grant to battery materials company NanoGraf and South 8 Technologies, developers of a novel liquefied gas electrolyte (LiGas). The companies will pair NanoGraf’s 3.8 Ah 18650 cell with South 8’s electrolyte for cold temperature and safety testing. The DoD award will fund… Read more »

TDK Ventures invests in Novalith clean lithium-extraction technology
Embargo til April 17 TDK Ventures has invested in lithium-extraction startup Novalith, which has developed a novel system for extracting battery-grade lithium from resource deposits. Novalith points out multiple drawbacks of current lithium production methods. Traditional ore mining involves the arduous process of finding lithium-containing ore, followed by major investments in infrastructure and time to… Read more »
Thermal runaway in EV battery packs: designing a mitigation strategy
Aspen Aerogels’ cutting-edge materials protect against thermal runaway Thermal runaway occurs inside a battery cell through a fault, a crash scenario or some other defect that causes the cell to release thermal energy through chemical reactions. That thermal energy increases the temperature of the cell, the increased temperature drives faster kinetics, and more heat is… Read more »
Alternatives to permanent magnet motors in EV traction applications
In my very first article for Charged over 10 years ago, I opined that the Switched Reluctance Motor, or SRM, would eventually come to dominate the EV traction market, if for no other reason than the fact that it is almost as cheap as dirt to manufacture. I won’t sprain my shoulder patting myself on… Read more »
Lubrizol introduces new sulfur-free driveline lubricant technology for EV transmissions and e-axles
Sponsored by Lubrizol. The explosion in EV uptake has created huge opportunities for innovations in the vehicle electrified powertrain, and the unprecedented rapid design of completely new lubricating fluids to allow the electrified powertrains to operate at their utmost efficiency. At the heart of the e-powertrain is the electric motor. Increasingly this is intentionally soaked… Read more »
Li-Bridge calls for building a domestic US battery supply chain
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 »
