The separator is a non-woven, porous material that physically isolates the zinc anode from the manganese dioxide cathode, preventing a direct short circuit. The electrolyte is a key ingredient in the energy conversion process, and its composition is central to the function of a 9 volt battery.

The External Anatomy and Terminals The first components you encounter are the terminals, the physical points where electrical current enters and exits the device. The cathode is a composite material known as manganese dioxide, mixed with carbon to improve conductivity, forming the positive electrode.
In the common alkaline variant, this electrolyte is a potassium hydroxide solution, a strong alkaline compound. Separating these two reactive electrodes is a porous, fibrous material soaked in an electrolyte solution, which acts as the ionic conductor while preventing the anode and cathode from touching and short-circuiting.
