摘要：PURPOSE:To obtain a silver (II) oxide cell with less increase of the internal resistance during storage by forming a lead-dioxide layer on the surface of a positive electrode shaped body, in the neutral aqueous solution. CONSTITUTION:260mg. of the mixture consisting of 47.5 parts of silver (II) oxide powder and 47.5 parts of silver (I) oxide powder is press-molded under 5t/ cm<2> pressure to a shaped body having a diameter of 9mm. and a thickness of 0.7mm.. Said shaped body is immersed for 60min into the aqueous solution containing 1.5gr. of lead nitrate dissolved into 1,000ml, water allowing lead dioxide to be deposited onto the surface, and then washed and dried. The amount of lead dioxide deposited onto the positive electrode thus formed is 0.3mg, and the results that the absorption rate for carbon dioxide is exceedingly small and the increase of the internal resistance during storage is little are shown in the figure.
