Researchers may have found ways to prevent dendrite formation in solid-state batteries. Their findings are described in the journal Nature Energy, in a paper by MIT graduate student Richard Park, MIT Professor Yet-Ming Chiang and researchers at MIT and other institutions. Chiang explained, “The only way you can reach the energy densities that are interesting… Read more »

MIT study details plunge in lithium-ion battery costs
MIT researchers analyzed three decades of studies that examined the decline in lithium-ion battery prices, and found that costs have dropped by 97 percent since they were first commercially introduced in 1991. This rate of improvement is much faster than many analysts had claimed, and is comparable to that of photovoltaic panels, which some had… Read more »
ArcelorMittal invests in electrical steel plant for EV motors
ArcelorMittal is investing €13 million in its plant in Saint Chély d’Apcher, France, which specializes in iCARe electrical steels for the automotive sector. The company has been undergoing a series of transformations as a supplier for the electromobility market. Its iCARe range of electrical steels for automotive traction motors is a flagship product range. The… Read more »
Nidec to acquire Mitsubishi Heavy Industries Machine Tool to support EV drive manufacturing
Nidec, a producer of motor application products based on “everything that spins and moves,” plans to acquire Mitsubishi Heavy Industries Machine Tool. Nidec has been engaged in the manufacture of reduction gearboxes and pressing machines through its subsidiary Nidec-Shimpo. After completion of the acquisition, Mitsubishi Heavy Industries Machine Tool will become Nidec-Shimpo’s third main business…. Read more »
New emissions scandal? Tests show PHEVs emit more pollution than claimed
Sometimes it seems automakers will try any powertrain technology in order to avoid selling battery-electric vehicles. First diesels, then hydrogen, were touted as ways to reduce CO2 emissions while still maintaining the fill-er-up-with-fossil-fuel business model (and continuing to crank out the colossal SUVs that carmakers claim consumers crave). Many electric purists have long suspected that… Read more »
How to ensure EV traction motor magnets aren’t pushed beyond their operating limits
Avoiding motor demagnetization: John Wanjiku, Technical Specialist at Mentor Graphics, explains the goals of a detailed traction motor design analysis. Neodymium permanent magnets are used in EV traction motors because of their powerful magnetic fields and relatively strong resistance to demagnetization, but they tend to lose their magnetism when exposed to excessive operating temperatures, opposing… Read more »
China cuts EV subsidies—Tesla Model 3 exceeds price limit
China has announced a cut to its subsidies on new energy vehicles (NEVs), effective immediately. It’s been something of a rollercoaster ride for the subsidies of late. In 2015, the government announced plans to end the subsidies this year. In January, it said there would be “no significant cuts” this year. In March it confirmed… Read more »
Workhorse C-Series electric delivery trucks earn EPA Certificate of Conformity
Electric truck maker Workhorse Group (NASDAQ: WKHS) has been around for a while—Charged wrote about the company’s plug-in pickup back in 2017—and it continues to make steady progress. Now the company has announced that its new C-Series electric delivery trucks have each received an EPA Certificate of Conformity, confirming that the new vehicles conform to… Read more »
MIT team develops novel solid electrolytes and pure lithium anodes
New research from MIT could lead to batteries that pack more power per pound and last longer. A new paper co-authored by Yuming Chen and Ziqiang Wang at MIT explores the idea of using pure lithium as the battery’s anode. The design is part of a concept for developing safe solid-state batteries by dispensing with… Read more »
