Abstract

The cycle performance of Li–O2 batteries is significantly enhanced by using a PU/SiO2/GF nanocomposite separator, which effectively protects the Li anode from corrosion by soluble oxidative intermediates from the ORR, and the dendritic growth of Li crystals during cycling is also inhibited.
