A dendrite-free and stable anode for high-performance Li–O2 batteries by prestoring Li in reduced graphene oxide coated three-dimensional nickel foam†
Abstract
Li-based reduced (r)GO-Ni (Li/rGO-Ni) was prepared by a thermal-infusion method. Li/rGO-Ni based symmetric cells have high cycling stability and small voltage hysteresis at various current densities. Furthermore, the Li/rGO-Ni based Li–O2 batteries exhibit good performances.
