Nano Prof Meng's Lab Finds Increased Battery Capacity By Controlling Oxygen Activity

A team of international researchers led by Dr. Shirley Meng 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. The discovery sheds light on how changing the oxygen composition of lithium-rich cathode materials could improve battery performance, particularly in high-energy applications such as electric vehicles. The findings were published July 1 in Nature Communications.
