The electrochemical performance of ZABs with Co-AC, NiMnCo-AC, NiMnCoO4-AC, and PtC/IrO2 cathodes. (A) The open-circuit potential of primary ZABs at the initial 3 h. (Inset) Setup of the primary ZAB with NiMnCo-AC. The OCV was detected to be 1.429 V by a multimeter. (B) Discharge curves of ZABs at various current densities. (C) A blue LED was powered by three series-connected ZABs. (D) Long discharge curves of ZABs with NiMnCo-AC at the current densities of 10, 20, and 50 mA cm−2. (E) The initial three charge–discharge curves of ZABs at the current density of 10 mA cm−2. (F) Cycling performance of ZABs at the current density of 10 mA cm−2. (G) The i-v polarization and power density curves of ZABs. (H and I) The OCV of flexible ZABs with NiMnCo-AC at original and bending circumstances. (J) An LED light with TBSI (Tsinghua-Berkeley Shenzhen Institute) signal was powered by three series-connected flexible ZABs. (K) Demonstration of charging smartphone by three series-connected flexible ZABs.
