When the chemicals in the electric cell are used up, the electric cell stops producing electricity. The electric cell is then replaced with a new one. In the case of rechargeable batteries (such as the type used in mobile phones, cameras and inverters), they are used again and again how?

Hint:An electrochemical cell is a device that can either produce electrical energy or use it to cause chemical reactions. The battery is made up of one or more cells that are connected together. A primary cell is the galvanic battery that is intended to be used once and then discarded, as opposed to a secondary cell, which is a rechargeable battery that can be recharged and reused with electricity.
Complete answer:
When the circuit is complete in a normal cell, electrons flow from the negative terminal to the positive terminal. The cell is said to be dead when all of the electrons pass to the positive terminal, and none remain in the negative terminal. The electrochemical reaction in the cell is generally irreversible, making the cell non rechargeable.
However, in a rechargeable battery, the electrons will return to the negative terminal and be used again before the entire charge has moved to the positive terminal. And this only happens with a specific type of cell, the rechargeable ones.
When all of the charges are in the positive terminal of the battery, you can supply a charge to it to transfer the charge back to the negative terminal, which is how the phone is charged. Secondary cells or storage cells may provide the current needed to recharge rechargeable batteries.
Note:The charge moves from negative to positive when you use it and back to negative when you charge it. The charge in a normal electric cell cannot switch from positive to terminal. The simplest example of a rechargeable battery is a lithium-ion battery.
