High-voltage current sensor platform adds 100-A RMS capability
Melexis has introduced the MLX91224 and MLX91225 isolated current sensors for high-voltage automotive and industrial applications. The devices provide current measurement up to 100 A RMS and are designed for applications, including electric vehicle (EV) powertrains, dc-dc converters, and ac and dc chargers. The sensors integrate the current conductor, sensing element, signal conditioning, and isolation…
Novelis expands coated aluminum for EV battery components
Novelis has expanded its coated aluminum portfolio for EV battery applications, with materials designed for structural and electrical components within the battery pack. The material combines automotive-grade aluminum sheet with a water-based coating applied before forming. The coating is designed to improve corrosion resistance and formability while remaining effective after stamping. It can also provide…
Scaling all-solid-state battery manufacturing
Factorial Energy and Mitsui Kinzoku Company have entered a joint development agreement to support the industrialization of Factorial’s Solstice all-solid-state battery platform. Mitsui Kinzoku develops sulfide-based solid electrolytes for all-solid-state batteries and is advancing its A-SOLiD sulfide electrolyte toward mass production at a dedicated facility in Saitama, Japan. Under the agreement, Mitsui Kinzoku will contribute…
Engineering reliable charging hubs for autonomous EV fleets
Autonomous ride-hailing fleets need somewhere to recharge between trips, and that’s often a dedicated charging hub rather than a public station. These hubs can look a lot like large dc fast charging sites, but they’re used very differently. A robotaxi may plug in several times a day, so the equipment accumulates wear far faster than…
Georgia facility advances lithium carbonate recovery from used batteries
TDK Ventures has invested in R3 Lithium as part of the company’s $15 million Series A funding round, supporting the expansion of domestic lithium carbonate recovery from recycled battery materials. R3 Lithium owns and is upgrading a commercial-scale lithium carbonate recovery facility in Covington, Georgia, where production of recycled lithium carbonate was demonstrated in 2025…
