To satisfy the energy storage needs of society in the long-term, an advance in battery energy density is required. The lithium–oxygen battery is one of the emerging opportunities available for enhanced energy storage. The challenge for the Li–O2 battery is the progress of development of the O2-cathode that allows reversible formation of Li2O2 in a stable electrolyte within its pores.
