Researchers from the Cockrell School of Engineering at The University of Texas at Austin have a cobalt-free high-energy lithium-ion battery that reduces the costs of producing batteries while boosting ...

How do Lithium-ion Batteries Work? Lithium-ion batteries are commonly used in a variety of electronic devices. Lithium-ion battery cathodes are a critical component of the battery. They store and ...

BANGOR, Maine, April 13 (UPI) --In an effort to bring down costs, General Motors, Tesla, Nissan and other automakers have pledged to start building cars with cobalt-free lithium ion batteries.

The first resemblance is its warranty. SVolt says it ensures it will work just fine for 15 years or 1.2 million km. That is almost 1 million miles: 745,645 miles, to be more precise. Just like the ...

University of California researchers and academics from four US national laboratories have devised a way to make lithium-ion battery cathodes without using cobalt – a metal that is rare, costly, and ...

Commercial lithium-ion batteries have always relied on cathodes that contain cobalt, but the expensive metal’s supply chain is fraught with issues. A new cobalt-free cathode could provide reprieve ...

Researchers offer a new mixture of metallic elements to serve as lithium-ion cathodes. This 'high-entropy doping strategy' is part of an effort to remove cobalt -- and expensive and geopolitically ...
