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 ...

Researchers from Hunan University have designed a layered oxide cathode for rechargeable lithium-ion batteries that achieves fast-charging performance, long life, and high safety using only an ...

In a discovery that could reduce or even eliminate the use of cobalt — which is often mined using child labor — in the batteries that power electric cars and other products, scientists at the ...

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 ...

FM Nirmala Sitharaman has announced that the government will fully exempt Basic Customs Duty (BCD) on cobalt powder, scrap of lithium-ion batteries, LED, zinc, and 12 other critical minerals The new ...

In a recent article published in the journal Nano Macro Small, researchers explored the synthesis of cobalt-tin (Co-Sn) sulfides to enhance the performance and stability of sodium-ion batteries (SIBs) ...

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 ...
