  • Lithium-air battery including a redox mediator and protective layer, and method of manufacturing the same
    Patent number: 11764428
    Abstract: Disclosed are a lithium-air battery including a redox mediator in an electrolyte and having a protective layer on an anode, and a method of manufacturing the same. The lithium-air battery includes an anode including a lithium metal, a protective layer positioned on the anode and including lithium fluoride (LiF), a cathode, and an electrolyte positioned between the protective layer and the cathode. Particularly, the electrolyte includes a halogen ion (X?) which is a redox mediator.

  • Soluble catalyst for lithium-air battery
    Patent number: 10069182
    Abstract: A soluble catalyst for a lithium-air battery is provided. The soluble catalyst including a redox mediator (RM) has an ionization energy of about 5.5 to 7.5 eV under vacuum or an oxidation potential of 3.0 to 4.0 V and is well dissolved in an electrolyte without reacting with the electrolyte. In addition, the soluble catalyst has a HOMO level in an original state (RM), which is less than a formation energy of lithium peroxide (Li2O2) but maximally close to the formation energy, and has a HOMO level in an oxidized state (RM+), which is greater than a HOMO level of the electrolyte.
