Hollow carbon fibers with diameters on the order of 30 nm were grown on a ceramic porous substrate, which was used as the oxygen electrode in lithium-oxygen (Li–O2) batteries. These all-carbon-fiber (binder-free) electrodes were found to yield high gravimetric energies (up to 2500 W h kgdischarged−1) in Li–O2cells, translating to an energy enhancement ∼4 times greater than the state-of-the-art lithium intercalation compounds such as LiCoO2 (∼600 W h kgelectrode−1). The high gravimetric energy…
