Figure 17. Schematic illustration of the experimental setup. (A) A model zinc-air battery with the cross-section view of the cell in the upper-left corner (electrochemical setup); (B) In-situ TIRDFM (reflected light is rejected)-based setup used to collect scattered light during the zinc-plating process^[56]; (C) Schematic diagram of a liquid battery holder for observing electrochemical reactions in the solution; (D) Cross-sectional view of the battery; (E) Design drawing of the MEMS chip of the electrodes; (F) Arrangement of the three electrodes on the chip^[57]. MEMS: Microelectromechanical system; TIRDFM: total internal reflection dark-field microscopy.
