pairing of the copper which has an electron affinity of 0.34 and the silver which has an electron affinity of 0.80 makes a strong battery.

Explanation:

All the Batteries of this world are made with two metals having different-different electron affinities. What do the phrase "electrons affinities " mean and how do these affinities affect the voltage of the batteries?

The Electron affinities are the energy change that occurs when electrons are added to atoms. The greater the attraction of the atoms to the electrons the more energy would released. If an atom has high electron affinity, the electron will be harder to gain The greater is the difference in metal affinities, the greater the voltage. That means, if you pair Coppers with Silver, the difference between their electron affinities would be (0.80-0.34) or, 0.46 and You can make a strong battery.
