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 »

A closer look at graphite—its forms, functions and future in EV batteries
Q&A with Graphex CEO John DeMaio Reading the EV press, you might assume that lithium, cobalt and nickel are the stars of the battery show—they get a lot of coverage, as pundits debate the relative merits of NMC and LFP cathode chemistries and agonize over looming shortages. Meanwhile, over in the anode, there’s an unsung… Read more »
KAUST discovers inorganic 3D foam that may improve anode performance
KAUST, a Saudi Arabian private research university, says that lithium batteries may soon enjoy enhanced efficiency, thanks to a highly ordered foam of molybdenum disulfide (MoS2) that it has discovered. KAUST reports that the complex hierarchical structure of the self-assembling foam allows it to easily and repeatedly soak up and then release large quantities of… 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 »
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 »
GreenPower to pilot electric school buses across West Virginia
GreenPower Motor, a manufacturer of medium- and heavy-duty EVs, has deployed electric school buses in three West Virginia counties as part of a pilot project to demonstrate e-buses in school transportation operations across the state. The company will soon be producing buses in the state—in August, the company opened a manufacturing facility in South Charleston…. 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 »
GreenPower’s new West Virginia factory could produce 600 electric school buses per year
GreenPower Motor Company, a manufacturer of electric medium- and heavy-duty vehicles, has cut the ribbon at its new South Charleston, West Virginia manufacturing facility. The facility, which is home to the company’s electric school bus manufacturing operations east of the Mississippi River, has been expanded by an additional 80,000 square feet. It is expected to… Read more »
innolectric and CBMM study soft magnetic materials to increase charging efficiency
A joint research project of EV component manufacturer innolectric and Niobium products company CBMM is studying the role of nanocrystalline magnetic materials in boosting EV charging efficiency. The research is testing a soft magnetic core material with niobium in an innolectric on-board charger. “To achieve the best possible results, the functional properties, thermal behavior and… Read more »
Meta Materials to buy assets and IP of Optodot’s battery separator and coating tech
Materials and surfaces developer Meta Materials has signed an agreement to acquire all the assets and intellectual property of Optodot, a nano-composite battery separator and coating technology company. The acquisition, valued at $48.5 million, includes 67 patents and 22 pending patents. One of Optodot’s patents is for its third-generation NPORE ECS (electrode-coated separator) technology. “Optodot… Read more »
