Novel Method for Floating Synthesizing Heavy Metal Particles as Flowing Anode of Zinc-Air Fuel Cell

[摘要] In this study, centrally hollow microspheres of zinc were synthesized. The microspheres were then mixed with KOH electrolyte to form zinc sol, which was coagulated and precipitated. Afterward, we employed a novel technique to enable the permanent floating of zinc particles, which involved stirring zinc sol with air using a magnetic stirrer. This resulted in the formation of foam in which the zinc particles permanently floated. We then added 65 wt% of the electrolyte (KOH) to prepare 35 wt% of zinc sol. We tested the cell and found the values of current density, specific energy, and electric capacity to be 7.41 mA/cm2, 840.14 Wh/kg, and 3023 mAh, respectively.
