As with many inventions there is no simple answer.
The electric cell was invented not discovered.
The Daniel cell (1836) is possibly the first example of electric cells, these were an improvement on the Leyden jars (1745), independently invented by Kliest and Musschenbroek. These were more like what we would refer to as capacitors.
Volta then improved these further to what we would recognised today as a battery. That is, several 'cells' connected together which he referred to as a 'Crown of Cups'.

Electron discovered by einstein probably that how fool
This particle was the electron in 1897 (J.J. Thomson).
J.J.Thomson has discovered the electron in 1897
The electron
i have no idea when it was discovered
the electron was first discovered in 1897 by Joseph john Thomson and the proton was discovered in 1913 by ernest Rutherford
The year of the electron discovery is considered 1896.
