Air-lithium battery

PURPOSE: To obtain an air battery with high output and high energy density by arragning a lithium negative electrode on one side of a solid electrolyte consisting of lithium nitride and a positive electrode consisting of aqueous alkali solution and active carbon on the other side. CONSTITUTION: The positive electrode can 1 consisting of SUS304 and such has the air vent 10 and the section 8 is laser-welded. For example, inside this positive electrode can 1 there is arranged the positive electrode 2 which consists of the active carbon with its average particle diameter of 0.1∼1μ, 5∼20%KOH water solution, Teflon powder, and the metal net 11. At the upper part of this positive electrode 2 there are arranged the solid electrolyte 5 consisting of Li 3 N and the negative electrode Li4. These sides are covered by the insulating material 6 consisting of ceramics or synthetic resin. The Teflon film is contained between the positive electrode 2 and the air vent 10 and is jointly used as a gas transparent and liquid leak resistant micro-porous film. The section between the negative electrode terminal 3 and the positive electrode can 1 is air-tightly melt-sticked by inorganic glass 7 such as borosilicate glass and such.
