NOVELTY - Air cathode (10) used for nonaqueous air battery, comprises: air cathode current collector (1) having porous structure, and air cathode layer (3) containing conductive material (2) and formed on air cathode current collector; where average supporting amount of conductive material in planar area of air cathode is (0.3-9, preferably 0.5-8) mg/cm2. The conductive material is powder carbon material. The air cathode current collector is current collector comprising carbon material.    USE - As air cathode used for nonaqueous air battery (claimed).    ADVANTAGE - The air cathode for nonaqueous air battery has great discharged capacity per unit area, whereas the air cathode of conventional nonaqueous air battery has a problem that its discharged capacity per unit area is small. The average supporting amount of conductive material in planar area of air cathode is 0.5-80 mg/cm2; which results in air cathode having increased discharged capacity per unit area. In the air cathode, the blocking due to discharge products (including Li2O and Li2O2 in the case of a lithium air battery) may be restrained. Otherwise, on the occasion when discharge products are caused in accordance with discharge, a conventional air cathode is so large in average supporting amount of conductive material that blocking due to discharge products is easily caused on surface and inside of air cathode and nonaqueous liquid electrolyte is easily hindered from moving. As a result, it is conceived that discharged capacity per unit area is decreased. On the contrary, with regard to the air cathode comprising specific average supporting amount of conductive material in planar area of the cathode, the blocking due to discharge products may be restrained to allow the air cathode with great discharged capacity per unit area. Thus the use of this air cathode provides nonaqueous air battery excellent in discharged capacity per unit area of the air cathode. Also, if blocking due to discharge products is caused in when charge starts, it becomes difficult for oxygen gas caused at the time of decomposing discharge products, to pass through for outside of air cathode. Then problem arises that charging voltage is increased and the discharge products may not be decomposed with high efficiency. The air cathode solves this problem because blocking due to discharge products is caused with difficulty. The use of conductive material comprising powder carbon material and air cathode current collector comprising carbon material further results in excellent corrosion resistance.
