Abstract
A cathode for a lithium air battery, the cathode including: an organic-inorganic composite material including a coating layer on at least one portion of a surface thereof, wherein the coating layer includes a positively charged silane compound and an ionic bond forming anion. Also a lithium air battery including the same, and a method of manufacturing the cathode.
Claims21
A cathode for a lithium air battery, the cathode comprising:
- an organic-inorganic composite material comprising a coating layer on at least a portion of a surface of the organic-inorganic composite material, wherein the coating layer comprises a positively charged silane compound and an anion capable of forming an ionic bond.
A method of manufacturing a cathode, the method comprising:
- adding a reactive compound to a porous carbonaceous material to bond a reactive functional group to a surface of the porous carbonaceous material to provide a functionalized porous carbonaceous material;
- adding a positively charged silane compound to the functionalized porous carbonaceous material to form a mixture;
- heat-treating the mixture to prepare an organic-inorganic composite material comprising a coating layer comprising a silane compound chemically bonded to the reactive functional group;
- washing the organic-inorganic composite material comprising the coating layer with a salt;
- and
- drying the washed organic-inorganic composite material to prepare an organic-inorganic composite material comprising a coating layer comprising an anion capable of forming an ionic bond.
