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.

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.

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 ...

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 ...

Lithium-based cells are the chemistry of choice for many battery applications due to their favorable power/weight and power/volume ratios, but also have a drawback with the well-known risks of fire ...

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 ...
