How do alkaline batteries work?
Alkaline batteries are a popular choice for powering various electrical devices, from small remote controls to larger flashlights and toys. These batteries use a basic chemistry to generate electrical power. Here’s a breakdown of how they work:
- An alkaline battery has a cathode (positive terminal) made up of manganese dioxide and a graphite rod (current collector).
- The anode (negative terminal) is made up of zinc powder, which is pressed and shaped into the required form.
- The electrolyte is a potassium hydroxide solution, which separates the two terminals and allows the flow of electrons to complete the circuit and generate electricity.
When the battery is connected to a device, an electrochemical reaction occurs between the anode and the cathode, causing electrons to flow through the circuit and power the device. The chemical reaction also produces hydrogen gas, which is absorbed by the electrolyte, and water, which remains within the battery.
As the battery discharges and the anode is consumed, the electrolyte begins to break down, and the battery voltage drops. Eventually, the battery will reach a point where it can no longer power a device, and it’s time to replace it with a new one.
