US solid-state battery technology developer Nuvvon’s polymer electrolyte has passed a series of nail penetration tests, which create a short circuit inside the cell to determine if the battery catches fire or explodes. In two sets of tests, which were conducted at The University of Texas at Austin (UTA), traditional 1 Ah cells of commercial… Read more »

Amprius SiCore battery cells power unmanned aircraft systems in Ukraine
The Astero ISR, a battle-tested unmanned aircraft system designed and built by Nordic Wing, a Danish-owned fixed-wing drone manufacturer, has been in use by Ukrainian forces since early 2023, and many improvements to the drone have been based on feedback from Ukrainian soldiers These drones are built for a hardened environment. The Astero ISR is… Read more »
Zeta Energy makes a breakthrough in lithium-sulfur battery technology
Cheap, abundant and sustainable. Sulfur may not be the most glamorous of elements—some may associate it with rotten eggs, stinky well water, or even the devil, as invoked in a country preacher’s fire-and-brimstone sermon. But as a component of an EV battery cathode, sulfur has a lot to offer. The yellow stuff is lighter and… Read more »
Advanced cooling methods for power electronics
One of the primary issues the power electronics engineer must address is the removal of waste heat—the well-known Arrhenius equation from chemistry/physics tells us that the operational life of any given electronic component will roughly double for every 10-11° C drop in its temperature. Power electronics devices on EVs are also under considerable pressure to… Read more »
