AbstractA tremendous amount of work is devoted to build an all-in-one energy storage equipment to meet the ever-increasing demand for flexible wearable electronics. At present, the flexible all-in-one zinc ion batteries have captured enormous attention owing to its high volume capacity, abundant reserve and robust security. Herein, the Mn-doped K0.23V2O5 nanobelts materials are innovatively prepared by introducing Mn and K ions into vanadium oxide, which will acquire an intensive conductivity and favorable Zn2+ storage. In the conventional aqueous zinc ion batteries, the Mn-doped K0.23V2O5 electrode offers a high discharge capacity of 269.1 mAh g−1 after 100 cycles at the moderate current density of 1.0 A g−1 and a remarkable cyclability (226.7 mAh g−1 after 5000 cycles at 10.0 A g−1). Moreover, the electrode also displays a good rate performance. Besides, the binder-free Mn-doped K0.23V2O5/CNT film is further constructed for flexible all-in-one batteries, which exhibits satisfactory cycling performance with high-capacity retention of greater than 84.1% after 2000 cycles under continuous bending. Thus, this work provides a facile strategy for new-generation convenient and wearable energy-storage facility.
