Abstract

Actually, Li-O₂ batteries can be served as flexible power sources with extremely high specific energy densities to meet the rising demand for flexible and wearable electronic devices. In this work, the electrochemical performance and flexibility of a Li-O₂ battery are demonstrated to be significantly enhanced by introducing a KH550–NH₄Cl-treated, KOH-activated, CNTs-grafted cotton fabrics cathode. The as-fabricated flexible cathode exhibits superior electrochemical performance, including a high specific capacity (22.4 mAh cm⁻² at 0.15 mA cm⁻²), an excellent rate capability, and a good cyclic performance for more than 250 cycles.
