hello sir,

 Batteries have three sections, an anode (- ), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a conventional battery) are snared to an electrical circuit. 

The synthetic responses in the battery causes a development of electrons at the anode. This outcomes in an electrical distinction between the anode and the cathode. You can think about this distinction as a shaky develop of the electrons. The electrons needs to adjust themselves to dispose of this distinction. Be that as it may, they do this with a specific goal in mind. Electrons repulse one another and attempt to go to a spot with less electrons. 

In a battery, the main spot to go is to the cathode. In any case, the electrolyte shields the electrons from going straight from the anode to the cathode inside the battery. At the point when the circuit is shut (a wire interfaces the cathode and the anode) the electrons will almost certainly get to the cathode. In the image over, the electrons experience the wire, lighting the light en route. This is one method for portraying how electrical potential makes electrons move through the circuit. 

Be that as it may, these electro chemical procedures change the synthetic concoctions in anode and cathode to make them quit providing electrons. So there is a restricted measure of intensity accessible in a battery. 

When you energize a battery, you alter the course of the stream of electrons utilizing another power source, for example, sunlight based boards. The electrochemical procedures occur backward, and the anode and cathode are reestablished to their unique state and can again give full power.
