Texas-based battery tech startup Group1 has launched the world’s first potassium-ion battery (KIB) in the popular cylindrical 18650 format. The battery outperforms Li-ion ones in key areas like ...

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 ...

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 ...

Today’s electric vehicles are predominantly powered by nickel-manganese-cobalt (NMC) lithium-ion batteries. However, the inclusion of cobalt in this type of batteries has been considered as ...

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 ...

Jeff Dahn's battery lab at Dalhousie University in Halifax, Canada, known for its Tesla ties, is working on a new Li-ion battery chemistry. The new battery cell will use a single-crystal, cobalt-free ...

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 ...

US researchers say they have developed a way to make cobalt-free lithium-ion battery cathodes, while Ford says it has broken ground on a new $5.6 billion production complex for electric vehicles and ...

Scientists are looking to identify alternatives to lithium-ion batteries that rely on cobalt, an African-mined metal drawing scrutiny over human rights issues and environmental problems. Cobalt offers ...

Cobalt is essential for powering our modern technology. The metal is commonly used to make lithium-ion batteries, which are found in items such as electric vehicles, computers, smartphones, and even e ...
