Sponsored by Aspen AerogelsThermal runaway propagation is a complex challenge. No matter the cell chemistry or pack architecture, lithium-ion batteries are at risk of experiencing a thermal runaway event. Although there is no one-size-fits-all solution, battery engineers do not need to reinvent the wheel when developing a solution to meet critical safety requirements. By understanding… Read more »

5 electric vehicle trends seen in 2022
Sponsored by Parker LordJust over a decade ago, a report by IDTechEx predicted 1.5 million battery-electric vehicle (EV) sales by the start of 2021—a prediction seen by many as overly optimistic. Yet, it turned out to be a significant underestimate by more than half. And there is no sign of EV sales slowing in 2022. In fact, Bloomberg… Read more »
Innovative approaches to electrified propulsion system development
Sponsored by AVL There are many ways to develop an e-drive system, or a vehicle with an e-drive system as the source of propulsion. Traditional development methods, while effective for some applications, also present some major challenges—especially when it comes to scalability. Technical and non-technical issues challenge developers and manufacturers in this propulsion system development… Read more »
Jaguar Land Rover to use Wolfspeed’s silicon carbide semiconductor tech in its next-gen EVs
Semiconductor manufacturer Wolfspeed will supply silicon carbide semiconductors for Jaguar Land Rover’s next generation of EVs. Wolfspeed’s technology will be used specifically in the vehicles’ inverter, managing the transfer of power from the battery to the electric motors. The new technology is scheduled to be used in Range Rover vehicles starting in 2024, and in… Read more »
Researchers study particle boundaries in cathodes, develop new NMC cathode design
Image shows single crystals of cathode material: (A) no internal boundaries and (B) internal boundaries visible. (Image by Argonne National Laboratory.) A research team has developed a new NMC cathode design that prevents cracking in cathode particles through a structure that doesn’t have boundaries between particles. “A different approach to avoid this cracking involves single-crystal… Read more »
Researchers achieve a breakthrough in the development of lithium metal batteries
A team of researchers working in collaboration with the Nagoya Institute of Technology has discovered a new mechanism to stabilize the lithium metal electrode and electrolyte in lithium metal batteries. The researchers say the new mechanism, which does not depend on the traditional kinetic approach, has the potential to enhance the energy density of batteries…. Read more »

Prototype interior permanent magnet synchronous motor achieves 100,000 rpm
A team at the University of New South Wales (UNSW) Sydney in Australia has built a new high-speed motor which can be used in EVs, large HVAC systems, high-precision CNC machines and the integrated drive generators in aircraft engines. Using its own optimization program, the team has built a prototype IPMSM motor with a patented… Read more »
Researchers create electrode with high energy capacity from nanosheets
A team of researchers has fabricated thick electrodes from two-dimensional materials in order to design an electrode for faster charging and higher energy capacity in lithium-ion batteries. “Two-dimensional materials are commonly believed [to be] a promising candidate for high-rate energy storage applications because it only needs to be several nanometers thick for rapid charge transport,”… 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 »
