Abstract
An air battery cathode including an organic-inorganic composite material including lyophobic nanopores, the organic-inorganic composite material including a porous metal oxide, and a lyophobic layer on a surface of a pore of the porous metal oxide and having a contact angle of greater than about 90°; and a binder. Also a lithium air battery including the cathode, and a method of manufacture the cathode.
Claims22
An air battery cathode comprising:
- an organic-inorganic composite material comprising lyophobic nanopores, the organic-inorganic composite material comprising
- a porous material, and
- a lyophobic layer on a surface of a nanopore of the porous material;
- and
- a binder.
A method of manufacturing an air battery cathode, the method comprising combining an organic-inorganic composite material and a binder to manufacture the cathode, wherein the organic-inorganic composite material is manufactured by:
- impregnating a porous material with a reactive compound comprising a reactive functional group bondable to the porous material;
- and
- chemically bonding the reactive compound to a surface of the porous material to form a lyophobic layer on the surface of the porous material to manufacture the organic-inorganic composite material.
