Answer:
In the process of the reaction, electrons can be transferred from the zinc to the copper through an electrically conducting path as a useful electric current. An electrochemical cell can be created by placing metallic electrodes into an electrolyte where a chemical reaction either uses or generates an electric current.

A chemical cell converts chemical energy into electrical energy. Most batteries are chemical cells. A chemical reaction takes place inside the battery and causes electric current to flow.
There are two main types of batteries - those that are rechargeable and those that are not.
A battery that is not rechargeable will give electricity until the chemicals in it are used up. Then it is no longer useful. It can be rightly called 'use and throw'.
A rechargeable battery can be recharged by passing electric current backwards through the battery; it can then be used again to produce more electricity. It was Gaston Plante, a French scientist who invented these rechargeable batteries in 1859
