Lithium-oxygen (Li-O2) batteries are promising due to their high theoretical energy density. However, the poor catalytic performance of the technology's air cathode impeded its commercialization.

Recently, a joint research group led by Prof. Bao Xinhe and Prof. Wu Zhongshuai from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) fabricated two-dimensional (2D) Mn3O4 nanosheets with dominant crystal planes on graphene (Mn3O4 NS/G) as efficient oxygen catalysts for Li-O2 batteries, achieving ultrahigh capacity and long-term stability.

This study was published in ACS Catalysis.
