Does peltier effect account for lose of voltage of the cell?

Question

The Peltier effect is the reverse of the Seebeck effect; a creation of a heat difference (between two joint) from an electric voltage.

This temperature difference gives rise to a seebeck voltage which is opposite the voltage of the battery. So we can resonably conclude that it can contribute to the loss of voltage of the battery, can't we?

Answer 1

It's not impossible, but it's not a reasonable conclusion. The Peltier effect is observable in very few materials, like Bismuth Telluride. But it uses current flow to transfer heat. The Seebeck effect could oppose the battery voltage, but it would be an exceedingly small effect. You would need a lot more evidence than just a voltage drop to conclude that the Seebeck effect was responsible.
