Iron trifluoride cathode could greatly increase energy density
Researchers from the University of Maryland and the DOE’s Brookhaven National Laboratory have developed a cathode material containing iron trifluoride (FeF3) that they say could triple the energy density of Li-ion batteries. Their research was published in Nature Communications. “Compared to the large capacity of the commercial graphite anodes used in lithium-ion batteries, the capacity of the cathodes is… Read more »
Honda and GM partner to develop next-gen battery
GM and Honda have agreed to develop new battery chemistry components in order to hasten their plans for future all-electric vehicles. They seek to improve power density, packaging size, and charging capabilities for their up-and-coming EVs. Honda intends to source the new modules from GM in the future. This is not their first partnership; they… Read more »

ON Semiconductor announces rugged automotive SiC Diodes
ON Semiconductor has introduced a robust line of automotive-grade silicon carbide (SiC) Schottky diodes. The AEC-Q101 diodes can handle high surge currents and are meant to operate from -55° to 175° C. There are several reasons why SiC diodes are ideal for automotive applications. They are smaller and cheaper compared to alternatives, have higher power densities, and create… Read more »
VW aims to produce solid-state batteries by 2025
The Volkswagen Group has invested approximately $100 million in California battery QuantumScape, following six years of collaboration with the firm. VW also announced that it aims to have a production facility for solid-state batteries by 2025. VW estimates that solid-state battery technology could more than double capacity compared with its current batteries, for example boosting… Read more »
Wolfspeed Technology introduces third-gen 1,200 V SiC MOSFET
Only one year after they were first introduced, Cree’s Wolfspeed Technologies has announced its third generation of 1,200 V SiC MOSFETs. Designed for EV powertrain applications, Wolfspeed claims that the MOSFET has the highest figure of merit on the market today, with low drain-source on resistance (RDS) performance and the industry’s lowest switching losses. Samples are currently available… Read more »
Webasto to acquire AeroVironment’s Efficient Energy Systems for $35 million
Automotive supplier Webasto is set to acquire AeroVironment’s Efficient Energy Systems (EES) branch, pending several more heaps of paperwork. The $35-million acquisition includes EES’s charging and docking technologies, further diversifying Webasto’s portfolio.
