A team of researchers has developed a flexible, rechargeable silver oxide-zinc battery with a five to 10 times greater areal energy density than state of the art. The battery also is easier to manufacture; while most flexible batteries need to be manufactured in sterile conditions, under vacuum, thi

In a new study, researchers explain why one particular cathode material works well at high voltages, while most other cathodes do not. The insights, published in the 19 June issue of the journal Science, could help battery developers design rechargeable lithium-ion batteries that operate at higher voltages.

…storage capability of a particular class of “lithium-rich” cathode materials—by using a carbon dioxide-based gas mixture to create oxygen vacancies at the material’s surface. Researchers said the treatment improved the energy density—the amount of energy stored per unit mass—of the cathode material by up to 30 to 40 percent.
