Understanding Carbon Zinc 9V Batteries: Inner Workings
At its core, a Carbon Zinc 9V battery is an electrochemical cell that converts chemical energy into electrical energy. It consists of a zinc anode, a manganese dioxide cathode, and an electrolyte paste composed of ammonium chloride and zinc chloride.
When the battery is connected to a circuit, a chemical reaction occurs between the zinc anode and the manganese dioxide cathode, facilitated by the electrolyte. During this reaction, electrons flow from the zinc anode to the manganese dioxide cathode through the external circuit, creating an electrical current.
The zinc anode gradually corrodes during this process, while the manganese dioxide cathode undergoes a reduction reaction. The electrolyte paste acts as a medium for ion transport, ensuring the continuity of the chemical reaction.
