Abstract:
We developed H2Ti5O11·xH2O on carbon cloth (HTO·xH2O/CC) as a binder-free Zn metal-free anode. This 'rocking chair' battery incorporated a ZnMn2O4/CC cathode, HTO·xH2O/CC anode, and a polyacrylamide-based electrolyte, and exhibited satisfactory flexibility and self-healing. It displayed recoverable capacities after four repetitions of cutting and healing, indicating a potential using as a foldable and wearable battery.
