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 »
NEO announces plans to integrate recycled silicon into silicon anode materials
NEO, a developer of silicon anode materials, reports that it has signed an MOU with an undisclosed Asia-based producer of high-purity silicon powder derived by recycling silicon by-product waste from solar photovoltaic cell and semiconductor manufacturing. The purpose, says NEO, is to significantly enhance price competitiveness of silicon anode materials for EV batteries by integrating… Read more »
This week’s webinar: A multi-physics approach to battery thermal management and runaway analysis
Thermal issues associated with the battery might affect its safety, reliability, lifetime, and performance. What if you can ensure the battery operates in safe temperature ranges while maximizing its performance, minimizing its degradation and avoiding hazardous conditions? Siemens offers an integrated battery design and thermal management workflow with multi-level modelling and multi-physics simulations. In this… Read more »
Kia EVs to use onsemi’s silicon carbide power module for traction inverters
onsemi has announced that its EliteSiC family of silicon carbide power modules has been selected for Kia’s EV6 GT model. onsemi says its power module enables high-efficiency power conversion from the DC 800 V of the battery to the AC drive for the rear axle. It also delivers package technology to minimize parasitics and thermal… Read more »
High-power and high-speed interconnect design considerations for electric and autonomous vehicles
With the converging automotive trends of vehicle electrification and Advanced Driver Assistance Systems (ADAS), the role of traditional automotive interconnects is evolving to meet more demanding performance requirements for key automotive application areas, including high-power interconnects specific to electric vehicles, and high-speed data interconnects required for ADAS control components which will ultimately evolve to fully… Read more »
Rice University announces new process to revive lithium-battery anodes for reuse
Rice University scientists have reported what they believe to be a partial solution to the mounting disposal problem of worn-out lithium-ion batteries. It relies on a unique “flash” Joule heating process they have developed to produce graphene from waste. The lab of Rice chemist James Tour is said to have reconfigured the process to quickly… Read more »
Ultium Cells to expand battery production by 40 percent in Tennessee plant
Ultium Cells, the battery cell manufacturing joint venture of LG Energy Solution and GM, plans to invest an additional $275 million in its Spring Hill, Tennessee plant to expand the facility’s battery cell output by more than 40 percent, from 35 GWh to 50 GWh. The company put $2.3 billion into the facility in April… Read more »
Ioneer in final permitting stage of its Lithium-Boron project in Nevada
Ioneer, an emerging US supplier of lithium and boron, has earned a notice of intent (NOI) from the Bureau of Land Management for its Rhyolite Ridge Lithium-Boron Project in Esmeralda County, Nevada. According to the company, the project’s purpose is “to provide environmentally sustainable lithium and boron to support development of domestic supply chains essential… Read more »
Verifying the origin of EV battery materials at the source: Traceability challenges, Part Two
Q&A with Bureau Veritas’s Stéphane Ponthieux Traceability—the process of documenting the source of a product and the links in its supply chain, has long been important in various industries (aerospace, food, pharmaceuticals). It’s now becoming a hot topic in the EV industry, because the Bipartisan Infrastructure Law (BIL) and Inflation Reduction Act (IRA), as well… Read more »
