Group14 Technologies, a provider of silicon-carbon composite materials for lithium-ion markets, has launched its first commercial-scale US factory to meet the demand for lithium-silicon anode materials. The 27,000-square- foot facility, located at Group14 HQ in Woodinville, Washington, will house a new R&D center and corporate offices, and is the first of several planned commercial manufacturing… Read more »
Sponsored by Herrmann Ultrasonics Aluminum and C\copper cables are commonplace between EV batteries, motors, and charging points. Ultrasonic welding can create a solid-state bond between dissimilar materials such as copper and aluminum. Cross-sectional areas of 95 mm² are common. However, demands for 120 mm² will require more powerful ultrasonic generators. Learn more about ultrasonic welding technology and the fundamentals of… Read more »
Leclanché has developed a new high-energy 65 Ah lithium-ion pouch cell to meet the demands of bus and truck manufacturers seeking increased EV range and operating time. The new GL 65 Ah G/NMC (graphite/nickel manganese cobalt oxide) cells are specially designed for energy-intensive applications. They provide 10% more energy and feature a 10% increase in… Read more »
Sponsored by Dymax Newly developed adhesives for active alignment of camera modules, optical components, and LiDAR assemblies in automotive applications cure rapidly “on demand” upon exposure to UV/LED light. These adhesives can also cure under low-temperature heat (80° C) to accommodate for any shadow areas. The products demonstrate excellent depth of cure, very low shrinkage,… Read more »
Volkswagen’s Braunschweig plant is expanding its production of EV battery systems. Following the first expansion stage, which established a maximum capacity of 250,000 battery systems, the second expansion stage has started up with the same capacity. Once the site is fully ramped up, it will be able to fit up to 500,000 batteries a year… Read more »
SAE International has announced revisions to SAE J3072 Standard: Interconnection Requirements for Onboard, Utility-Interactive Inverter Systems and SAE J2847/3 Recommended Practice: Communication for Plug-in Vehicles as a Distributed Energy Source. The updated EV charging documents will play a role in advancing automotive requirements for distributed energy resources (DER) projects. The revisions to SAE J3072 establish… Read more »
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 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 »
LG Chem has launched what it says is the largest carbon nanotube (CNT) plant in Korea. The company is targeting the growing market for CNT, often used as a cathode material for EV batteries. CNT has the same level of electrical and thermal conductivity as copper and diamond, and 100 times the strength of steel. … Read more »
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 »
