THE POSITIVE ELECTRODE OF LITHIUM-AIR BATTERIES

摘要

The present invention relates to a lithium-air battery. As a positive electrode having pores in the form of a fabric or mesh form of a carbon nano-tube (CNT) fabric, the positive electrode for a lithium-air battery comprises a first electrode on an upper layer on which the pores are big; and a second electrode on an under layer on which the pores are relatively small. In addition, the size of the pores of the first electrode is 15 μm, and the size of the pores of the second electrode is 12 μm. Therefore, a humidity content degree of an electrolyte according to a shape of a capillary tube can be maximized, so discharge capacity is expected to be more increased than that of a previous art.
