The present invention relates to a cathode material for a lithium-air battery and a method of manufacturing a cathode using the same. The cathode material of the present invention includes a solvent component and thus includes an electrolyte in a small amount compared to a conventional cathode material, thereby reducing the weight of a cathode manufactured using the cathode material, ultimately increasing the energy density of a lithium-air battery including the cathode.

The present invention provides an all-solid ion battery having improved stability and power characteristics and comprising: a powder-form solid electrolyte; a powder-form electrode active material; a first conductive polymer coating film coated on at least a portion of the solid electrolyte and capable of transporting ions; and a second conductive polymer coating film coated on at least a portion of the electrode active material and capable of transporting ions and electrons.

All-solid ion battery

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 (LiO) 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.
