Schematic representation of the fabrication of ZAMBs and demonstration of applicability of these fabricated microbatteries

Caption

Top: Zn and Co/Ni electrodeposition for anode and cathode, respectively, to fabricate CN-ZAMB (Inset of the figure illustrates the reversible Zn ⇌ ZnO conversion at the anode and the bifunctional ORR/OER processes at the cathode, facilitated by the presence of electrolyte ions such as NH4⁺, Zn2⁺, and Cl− and H2O molecules). Bottom: (L) Digital photographs of the Au IDE chip having total area 2.25 cm × 0.75 cm) and active area (1.15 cm × 0.6 cm), CN-ZAMB and Pt-ZAMB. (R) Three Pt-ZAMBs in series effectively powered an indoor–outdoor thermometer with a hygrometer clock.
