An international team of researchers has demonstrated a new way to increase the robustness and energy 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.
