Patent ID: 8883358

Claim:
A lithium air secondary battery having a negative electrode member which has metal ions occluded therein and emits metal ions, a positive electrode member which ionizes oxygen, and a separator which is impregnated with an electrolyte and disposed between the negative electrode member and the positive electrode member, the lithium air secondary battery being characterized in that the positive electrode member comprises at least a base material, a carrier, a catalyst, and a binder, wherein the catalyst is a metal oxide catalyst, the positive electrode member further includes a current collector and a metal porous material which is a nickel (Ni) felt functioning both as the carrier and the current collector, the Ni felt has a specific surface area of 0.03 m 2 /g or more and a pore diameter of 10 nm to 450 μm, and the carbon material weight ratio represented by the following formula in the positive electrode member is 50% or less: Carbon material weight ratio (%)=(Weight of the carbon material contained in the carrier)/(Weight of the carrier+Weight of the catalyst+Weight of the binder)×100.
