PURPOSE:To improve adhesion to a collector and utilization factor of an active substance and to increase discharge current by forming a thin type air battery using a negative electrode in which negative electrode active substance adheres to the collector. CONSTITUTION:A gas diffusion electrode 4 is electrically connected with a positive collector 1 of thin type air battery, wherein oxygen in the air diffused through an air hole 9 on the collector 1 is electrochemically reduced on the electrode 4. Also, a negative electrode active substance 6 is stuck to a thin metal foil or a film type negative electrode collector 7, and a separator 5 is interposed between the negative electrode active substance 6 and an electrode 4. The negative electrode active substance 6, prepared like ink by the use of powdered heat fusion resin, organic binder and solvent, is applied to the negative electrode collector 7 and dried to adhere. Thus, a thin type air battery with excellent polarization characteristics, appropriate properties to large current discharge, a low internal resistance and a large discharge capacity is manufactured. |
