MIT engineers are building a 1-megawatt (MW) motor to help facilitate the electrification of larger aircraft. The team has designed and tested the motor’s primary components and proved that the connected components can generate 1 MW of power at a weight and size comparable to current compact aircraft engines. The team anticipates a battery or… 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 »
ICCT study: Battery-electric trucks emit 63% less GHG emissions than diesel
A favorite trope of the “better stick with oil” crowd is that EVs aren’t any cleaner than ICE vehicles, because fossil fuels are consumed to manufacture and to charge them. Of course, all human activities have environmental footprints, but over the past decade, numerous studies have affirmed the lower lifecycle emissions of EVs compared to… Read more »
Kaluza and Mitsubishi collaborate on Japanese smart EV charging service
Mitsubishi and energy software platform Kaluza have launched what they say is the first telematics-based smart charging service in Japan, following similar Kaluza deployments in North America, Europe and Australia. Smart charging technology, which enables EVs to charge during times of low demand when energy is cheaper and greener, helps to alleviate network balancing issues…. Read more »

Ioneer in final permitting stage of its Lithium-Boron project in Nevada
Ioneer, an emerging US supplier of lithium and boron, has earned a notice of intent (NOI) from the Bureau of Land Management for its Rhyolite Ridge Lithium-Boron Project in Esmeralda County, Nevada. According to the company, the project’s purpose is “to provide environmentally sustainable lithium and boron to support development of domestic supply chains essential… Read more »
New electrode material preserves its volume, solving a major limitation of solid-state batteries
Solid-state batteries (SSBs) offer several potential advantages over current lithium-ion batteries, including improved safety and faster charging. However, SSBs suffer from a problem that limits their durability. When lithium ions are inserted into or extracted from the electrodes, the crystalline structure of the material changes, making the electrode expand or shrink. These repeated changes in… Read more »
Nouveau Monde Graphite, Panasonic and Mitsui to develop graphite project in Québec
Nouveau Monde Graphite, Mitsui and Panasonic Energy have entered into a framework agreement to enable the next development steps of NMG’s ore-to-battery-market integrated graphite project in Québec. The deal includes a multi-year offtake agreement between NMG and Panasonic Energy for a significant portion of NMG’s active anode material. Also, an investment of US$50 million from… Read more »
Advanced Thermal Barriers: How To Transform Your Thermal Runaway Mitigation Strategy
Battery engineers face the challenge of maximizing a vehicle’s performance while optimizing thermal runaway propagation protection. In this webinar, we will explore the role of compression pads and cell-to-cell barriers in managing mechanical and thermal energy inside modules and/or packs. Attendees will develop an understanding of possible solutions, including foams, fibers, foils, and aerogels. We… 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 »
