Power electronics thermal limits and how to not exceed them

To someone who isn’t involved in power electronics design, it might seem unreal that the amount of power a component can handle depends more on how effectively waste heat can be removed from it than it does on the specific electrical ratings. Sure, the voltage and current ratings are important (especially the voltage rating), but… Read more »

Umicore and Idemitsu Kosan team up to develop cathode material integrated with solid electrolyte

Umicore, a materials technology and recycling company, and oil company Idemitsu Kosan have reached an agreement to co-develop catholyte materials, which integrate cathode active materials (CAM) with solid electrolytes, for all-solid-state battery applications. Since Umicore began work on CAMs for solid-state batteries in 2017, it has established some patents in the area. “Based on more… Read more »

All 50 states, DC and Puerto Rico have submitted plans for national EV charging network

The National Electric Vehicle Infrastructure (NEVI) Formula Program, part of the Bipartisan Infrastructure Law (BIL) requires each state and territory to submit an EV Infrastructure Deployment Plan (EVIDP) in order to qualify for its share of the first round of the $5 billion of infrastructure formula funding (IFF) that will be made available over 5… Read more »

Researchers find additive can limit dendrite growth

A research team led by Dr. Hongyi Li and Dr. Tetsu Ichitsubo, both of Tohoku University in Japan, found that a multivalent cation additive can limit dendrite growth in rechargeable batteries by modifying the solvation structures of lithium or sodium ions in electrolyte. In an article published in Cell Reports Physical Science, the researchers say:… Read more »

VW’s Elli and Mitnetz Strom launch pilot for smart grid/EV integration

Elli, a brand of the Volkswagen Group, and German grid manager Mitnetz Strom have launched a pilot project to test the integration of EVs with a smart electrical grid. The Innovation Impulse for Future-Proof Grid Integration of E-Mobility project is intended to provide insight into what a practical implementation of smart charging could look like…. Read more »

Mitsubishi Chemical Holdings expands its anode materials business

Mitsubishi Chemical Holdings Group (MCHG) plans to increase its production capacity of natural graphite anode materials in China from 2,000 tons to 12,000 tons per year. MCHG’s Chinese subsidiary Qingdao Lingda Kasei produces spherical graphite for the anode materials, which another Chinese subsidiary, Qingdao Anode Kasei, then uses to produce anode materials for lithium-ion batteries….

Rice researchers find misaligned crystallites in cathodes limit lithium flow

Researchers at Rice University have found that stress between misaligned crystallites in cathodes limits the flow of lithium. In an article published in ACS Energy Letters, the researchers write: “As an important battery cathode material, reaction distribution in lithium iron phosphate (LiFePO4) has been extensively studied in dispersed particle systems, but remains poorly understood for… Read more »
