The Biden Administration today announced the recipients of nearly $1 billion of the Environmental Protection Agency’s (EPA) 2022 Clean School Bus Program rebate competition. In other words, that means thousands of new electric school buses will soon hit the road across the US.
Ford (F) reports its third-quarter earnings Wednesday after the bell. Although analysts expect revenue to climb YOY, earnings growth will be harder to achieve as the company has already warned investors of an over $1 billion impact from supply chain-related costs. Take a look at the Ford 2022 Q3 earnings preview below to see what you can expect later.
One of the options Starlink customers have been waiting on, for quite a while, is the ability to use Starlink terminals while in motion. With Starlink Maritime the company released the ability to use the high-speed internet while in motion out at sea, but at last, there is an official option for customers who want to mount a Starlink terminal on top of their RV or other vehicles for in-motion use.
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 fabricate a cobalt-free layered cathode with extremely high heat tolerance and stability over repeated charge and discharge cycles,” said research team member Huolin Xin. “This achievement resolves long-standing safety and stability concerns around high-nickel battery materials, paving the way for broad-based commercial applications.”
Working with researchers at four US national laboratories, Huolin Xin, UCI professor of physics & astronomy, has found a way to fabricate lithium-ion batteries without using cobalt, a rare, costly mineral extracted under inhumane conditions in Central Africa. Steve Zylius / UCI
“The highly stable structure is capable of withstanding more than 1,000 cycles and high temperatures, which makes it comparable to cathodes with much lower nickel content,” says UCI News.
In an article published in Nature, the researchers write: “Combining X-ray diffraction, transmission electron microscopy and nanotomography, we find that the cathode exhibits nearly zero volumetric change over a wide electrochemical window, resulting in greatly reduced lattice defects and local strain-induced cracks.”
“The combination of the different methods at NSLS II [National Synchrotron Light Source II] beamlines enabled the discovery of a trapping effect of oxygen vacancies and defects inside the material, which effectively prevents the crack formation in the HE-LMNO secondary particle, making this structure extremely stable during cycling,” says research team member Mingyuan Ge.
