Freudenberg introduces new conductive seals for electric motors

Freudenberg Sealing Technologies is introducing a new generation of electrically conductive seals at the virtual 2021 Vienna Motor Symposium. The seals are designed to prevent bearing damage caused by electrically-induced corrosion and to decrease electromagnetic interference. The power semiconductors in an inverter are often positioned directly above the motor. Silicon carbide semiconductors, which are often… Read more »

Rio Tinto achieves battery-grade lithium production at California plant

Rio Tinto has commenced production of battery-grade lithium from waste rock at a lithium demonstration plant at the Boron mine site in California. The demonstration plant is the next step in scaling up a lithium production process developed at Boron, to recover the mineral and extract additional value out of waste piles from over 90… Read more »

SABIC introduces new dielectric film for high-voltage capacitors in EV inverters

SABIC has introduced its new 5-micron ELCRES HTV150 dielectric film for high-temperature, high-voltage capacitor applications such as EV traction inverters. The company says its new film withstands temperatures up to 150° C. The film is intended to support the transition from conventional silicon-based semiconductors to next-generation, wide-band-gap silicon carbide (SiC) technologies, improving inverter efficiency.  “Multiple… Read more »
