Scientists say they have observed how the instability of vanadium disulfide in lithium-ion batteries occurs and claim to have solved the problem by applying a nanolayered titanium disulfide coating.

(Nanowerk Spotlight) Motivated by the outstanding performance of graphene, graphene-like 2D materials have been intensively investigated, such as topological insulators, transition metal ...

The new supercapacitor performs far better than earlier versions. It is less likely to self-discharge or short circuit. Specifically, it has an operating voltage window three times larger than before.

Magnesium batteries are safe -- unlike traditional lithium ion batteries, they are not flammable or subject to exploding -- but until now their ability to store energy has been limited. Researchers ...

Scientists have successfully developed a method to chemically exfoliate molybdenum disulfide crystals into high quality monolayer flakes, with higher yield and larger flake size than current methods.

An Israeli company has recently tested one of the most shock-resistant materials known to man. Five times stronger than steel and at least twice as strong as any impact-resistant material currently in ...

It took just three months in the fall of 1972 for Stanley Whittingham to conjure up the concept for the battery that changed the world. Whittingham, a 31-year-old Oxford-educated chemist, thought he ...

There are a handful of ways to produce hydrogen fuel without emitting carbon into Earth’s atmosphere. One involves using electricity to split water into hydrogen and oxygen. This method, known as ...

Magnesium batteries offer promise for safely powering modern life -- unlike traditional lithium ion batteries, they are not flammable or subject to exploding -- but their ability to store energy has ...
