Researchers develop cobalt-free cathode using high-entropy doping

A team of researchers from UC Irvine and four national laboratories has fabricated a cobalt-free cathode for lithium-ion batteries. The researchers relied on doping using HE-LMNO and magnesium, titanium, manganese, molybdenum and niobium inside the structure to fabricate a high-nickel cathode. “Through a technique we refer to as ‘high-entropy doping,’ we were able to successfully… Read more »

Delta Electronics demonstrates 400 kW solid-state transformer-based EV charger

Delta Electronics (Americas) demonstrated a next-generation SiC MOSFET solid-state transformer-based 400 kW EV charger at a recent event attended by representatives of project partners GM, DTE Energy and NextEnergy. Delta’s “extreme fast” EV charger uses a three-phase 13.8 kV medium-voltage SiC MOSFET SST topology. It provides 500 A of charging current, and the company claims… Read more »

ORNL to lead research center on polymer electrolytes

The DOE’s Oak Ridge National Laboratory (ORNL) has been chosen to lead an Energy Frontier Research Center (EFRC) on polymer electrolytes for energy storage applications, including fuel cells and solid-state EV batteries. “The EFRC program sponsors fundamental research to accelerate scientific breakthroughs needed to strengthen the US energy economy,” says ORNL. “Centers bring together multidisciplinary… Read more »

Oil wells could soon be pumping lithium in Alberta

Everybody loves lithium, but mining it does have an environmental footprint. Everybody (around here) hates oil, which has a much bigger footprint. But what if I told you that there’s a way to extract lithium from existing oil wells, and that it’s not only greener than other lithium extraction methods, but could even clean up… Read more »
