Researchers have identified what makes a common electrolyte additive so effective at improving the performance of batteries using a lithium cobalt oxide cathode

28-Sep-2022

Nitriles—an organic compound with a carbon atom triple-bonded to a nitrogen atom—are commonly added to the electrolyte formula for batteries using a lithium cobalt oxide cathode, making such batteries come much closer to realizing their full theoretical performance. Until now, battery researchers ...

Researchers developed a sulfur oxidation-reduction (redox) mediator to improve lithium–sulfur battery’s sluggish reaction kinetics which has limited the battery’s energy density

24-Jun-2022

Lithium-sulfur batteries hold strong promise as next-generation energy storage devices because of their ultrahigh theoretical energy density. However, the actual energy density of lithium–sulfur batteries is far from the theoretical value because of the cathode’s severe limitations caused by the ...

Heterogeneous photocatalysis can help scientists sustainably control products and byproducts of chemical reactions, including reducing CO₂

03-Jun-2022

Controlling the products and byproducts of a chemical reaction is called selectivity. Scientists are trying to find better ways to control selectivity in industrial chemical reactions to improve the quality of the chemical products, reduce wasteful byproducts, and reduce harmful byproducts, like ...
