In this paper, we present analysis of air cathode performance, taking into account both electrode passivation and transport resistance raised by insoluble products. Both effects are theoretically evaluated and compared. Validation is carried out against experimental data under low currents. The effects of electrode pore structure, such as porosity and tortuosity, on both the influence of insoluble precipitates and discharge capability are investigated.

CoSb3 nanoparticles wrapped with N-doped carbon layers have been prepared and showed excellent catalytic activities both for ORR and OER. A real rechargeable zinc–air battery with CoSb3@NCL-30 catalyst as air cathode exhibited outstanding electrochemical properties.

Synthesis of hyper branched polymer (HBP) based electrolyte has been examined in this study. A real world lithium-air battery cell was fabricated using the developed HBP electrolyte, oxygen permeable air cathode and lithium metal as anode material. Detailed synthesis procedures of hyper branched polymer electrolyte and the effect of different operation conditions on the real-world lithium-air battery cell were discussed in this paper. The fabricated battery cells were tested under dry air with 0.1mA∼0.2mA discharge current to determine the effect of different operation conditions such as carbon source, electrolyte types and cathode processes. It was found that different processes affect the battery cell performance significantly. We developed optimized battery cell materials upon taking into account the effect of different processes. Several battery cells were fabricated using the same optimized anode, cathode and electrolyte materials in order to determine the battery cells performance and reproducibility. Experimental results showed that the optimized battery cells were able to discharge over 55 hours at over 2.5V. It implies that the optimized battery cell can hold charge for more than two days at over 2.5V. It was also shown that the lithium-air battery cell can be reproduced without loss of performance with the optimized battery cell materials.

Rechargeable alkaline zinc-air batteries promise high energy density and safety but suffer from the sluggish 4 electron (e−)/oxygen (O2) chemistry that requires participation of water and from the electrochemical irreversibility originating from parasitic reactions caused by caustic electrolytes and atmospheric carbon dioxide. Here, we report a zinc-O2/zinc peroxide (ZnO2) chemistry that proceeds through a 2e−/O2 process in nonalkaline aqueous electrolytes, which enables highly reversible redox reactions in zinc-air batteries. This ZnO2 chemistry was made possible by a water-poor and zinc ion (Zn2+)–rich inner Helmholtz layer on the air cathode caused by the hydrophobic trifluoromethanesulfonate anions. The nonalkaline zinc-air battery thus constructed not only tolerates stable operations in ambient air but also exhibits substantially better reversibility than its alkaline counterpart.
