a Voltage profiles of the Zn–Cu cell between 1.6 and 0.4 V at 400 mA g−1. Cycling performance of the Zn–Cu cell b between 1.6 and 0.4 V at 800 mA g−1 and c between 1.6 and 0.9 V at 3000 mA g−1. d Self-discharge test. The fully charged cell was rested for 10 hours before the discharge process was started. e Schematic illustration of the rechargeable Zn–Cu battery for the flexible cell configuration. f The flexible Zn–Cu battery powering a digital timer before and after cutting.
