Furthermore, as the battery is being discharged, the lithium anode exhibits a remarkably high specific capacity and a comparatively low electrochemical potential (versus the standard hydrogen electrode (SHE) at −3.04 V), ensuring ideal discharge capacity and high operating voltage . 2.1. Basic Principles of Lithium–Oxygen Batteries
Zhou’s research team has effectively created a high-performing lithium-ion oxygen (Li–O 2) battery by utilizing commercially available silicon (Si) particles as the anode . A robust solid–electrolyte interface (SEI) coating was formed on the surface of the silicon (Si) anode.
Zn–oxygen batteries use Zn as an anode instead of Li, (7) despite allowing a narrower difference of potential than Li-oxygen batteries using organic electrolytes. The use of Zn enables the use of safer and nonflammable aqueous electrolytes and reduces the stability risks in comparison with other metal–air configurations.
Analysis of the rate of reaction between singlet oxygen and the solvent suggests that during a typical cycle of the lithium–oxygen battery, singlet oxygen would be responsible for approximately 0.002% capacity loss each cycle, which is not consistent with the 5–10% found in practice.
One of the challenges inhibiting the practical application of lithium–oxygen batteries is the unavoidable liquid electrolyte evaporation accompanying oxygen fluxion in the semi-open system, which leads to safety issues and poor cyclic performance.
Conclusions In this work, we propose an innovative full-sealed lithium-oxygen battery (F-S-LOB) concept incorporating oxygen storage layers (OSLs) and experimentally validate it. OSLs were fabricated with three carbons of varying microstructures (MICC, MESC and MACC).
