A closer look at brushed AC motors in EVs
Everything old is new again: BMW’s fifth-generation eDrive features a wound-field synchronous AC motor Brushed DC (and AC/DC universal) motors are much maligned for a number of reasons, but one of the chief—if, perhaps, somewhat exaggerated—complaints is that the graphite brushes, and the segmented copper commutator they ride on, wear out over time, all the while producing… Read more »
ONE’s hybrid battery pack combines the best aspects of two chemistries to deliver 600 miles of EV range
Q&A with ONE CTO Dr. Steven Kaye. There is a wide range of characteristics that describe the performance of any given battery chemistry: energy density, specific energy, specific power, discharge efficiency, self-discharge rate, cycle life, calendar life, and—not the least important—cost. Some types of Li-ion chemistries are really good in a few characteristics but fall… Read more »

2024 Chevrolet Blazer EV: Chevy previews a mass-market electric SUV
Mid-size five-seat crossovers are a huge segment, and Chevy wants yours to plug in—next year. Chevrolet, it seems, doesn’t want to scare potential shoppers by offering up electric vehicles that stress too heavily the fact they’re … well, different. An advance preview of the upcoming 2024 Chevrolet Blazer EV suggested it’s very much a Chevy… Read more »
Researchers develop new method for making thin and oxide-based solid-state electrolytes
A team of researchers from MIT and Samsung have invented a new approach for manufacturing oxide-based and thin solid-state electrolytes that doesn’t require sintering. In an article published in Energy & Environmental Science, the researchers write: “We report a ceramic manufacturing method termed sequential decomposition synthesis (SDS), which results in ceramic films with thicknesses between… Read more »
Brookhaven researchers describe benefits of electrolyte additive
A team led by researchers at DOE’s Brookhaven National Laboratory has investigated the benefits of a lithium difluorophosphate additive for electrolytes in lithium batteries with nickel-rich layered cathodes. According to Brookhaven, the possibility of high-energy-density cells composed of nickel-rich layered cathodes and lithium metal anodes is limited by processes that reduce their capacity. In an… Read more »
