As shown in FIG.1,an air-tightly sealed container 1 was formed at all of the container side wall 2,the cylindrical portion 3 and the bottom plate 7 out of covar,i.e.,an alloy of Fe--Ni--Co (the thermal expansion coefficient of which was 5.0×10-6 /°C.),and a covar pin was sealed as a terminal to the container 1 with glass of a low Batteries fifty years of materials development Oct 01,2000·After lead/acid,nickel/cadmium is the most widely used rechargeable battery.The cell operating voltage (1.20 V) is slightly less than that of Ni/Fe (1.25 V) and the mass of cadmium is higher than that of iron.Taken together,these two factors lead to a specific energy for the battery (3040 Wh/kg) which is nearer to that of lead/acid than
