Non-rechargeable batteries are an example of Galvanic cells or Voltaic cells.

Electric cell and its types:
- An Electric cell or electrochemical cell consists of two electron conductors separated by an ionic conductor and linked by an electron conductor.
- The ionic conductor is called the
- The electron conductors separated by the electrolyte are called
- The electron conductor used to link the electrodes is often a metal wire, such as copper wiring.
Types of Cell:
There are two fundamental types of electrochemical cell: Galvanic and Electrolytic.
- Galvanic cells (Voltaic cells):
- They convert chemical potential energy into electrical energy.
- The energy conversion is achieved by spontaneous redox reactions producing a flow of electrons.
Ex: Non-rechargeable batteries
- Electrolytic cells:
- They are driven by an external source of electrical energy.
- Electrolytic cell is any device in which electrical energy is converted to chemical energy and vice versa.
- A flow of electrons drives non-spontaneous redox reactions.
Rechargeable batteries are examples of both types of cell: They operate as galvanic cells when they are powering a device and as electrolytic cells when they are being recharged.
