Question

ok, how do batteries work? who invented the modern battery? and how does the battery made by that inventor differ from the ones we use today?

Answer 1

Batteries work by spontaneous loss of electrons from an anode such as a zinc plate, which travel outside the battery to light the light or ring the doorbell. Zinc ions travel across the cell to, let us say a copper cathode. At the copper cathode, the electrons coming back through the external circuit from having lit the light or rung the bell liberate hydrogen gas from the acid electrolyte.

The battery was originally called a voltaic pile, made by Alessandro Volta from sheets of zinc and copper interleaved with cardboard and leather, and everything soaked in salt solution. This is what we would call a wet cell, like our car batteries rtoday. Today, we have dry cells with zinc cans, manganese dioxide fillers, impregnated with ammonium chloride solution. and carbon electrodes.
