Use and exposure Silver is a very ductile and malleable precious metal. A major use of silver is as jewelry and silverware made from sterling silver and standard silver for traditional purposes. Silver also is used in photography and to make solder and brazing alloys, electrical contacts, and high-capacity silver-zinc and silver-cadmium batteries. Silver has the highest electrical conductivity of all metals—even higher than copper. ... 

Silver has a significant effect in delaying the discontinuous precipitation reaction as well as the overageing of calcium precipitates [90]. Silver also increases the corrosion resistance of lead-calcium tin alloys — particularly under conditions that simulate end-of-discharge (high pH) conditions — and improves the cycle-life and capacity of VRLA batteries. Silver decreases the thickness of the PbO layer but produces a harder, more compact, corrosion layer than tin. Silver does not, however, increase the conductivity of the corrosion layer. 

When high-conductivity electrolytes, in particular RbAg4l5, were discovered they opened the way for the development of batteries for higher discharge current. A battery with such an electrolyte can have a silver anode and an iodine cathode. In the course of the operation of batteries, silver is dissolved and the silver ions migrate through the solid electrolyte and react with the iodine ions produced in the cathodic reaction the final reaction product is silver iodide, Agl. 

Primary batteries. Silver compounds such as AgO are used as cathode materials for making high-capacity silver-zinc and silver-cadmium primary batteries. Silver paints are used for making printed circuits. 

In modern batteries silver oxide is used as the positive pole while zinc is the negative. 

Intercetl Connections. In a series-arranged battery of pile constraction, the anode of one cell is connected to the cathode of the adjacent cell. To accomplish this without producing a short-circuited cell, an insulating tape or film is placed between the electrodes on nonsilver batteries. For silver batteries silver foil is used alone or in conjunction with an insulating tape.
