This video uses 3D animation to explain the inner workings of an alkaline battery. It details the chemical reactions that produce energy, the components of the battery, and how electrons flow to power devices.
Key Takeaways
Battery Components: Alkaline batteries contain a plastic wrapper, steel casing, cathode (Manganese oxide and graphite), a fibrous barrier, an alkaline electrolyte (potassium hydroxide), and an anode (zinc powder and gelling agent).
Chemical Reactions: The battery's energy comes from chemical reactions. Oxidation (at the anode) releases electrons, while reduction (at the cathode) consumes them.
Electron Flow: Electrons released during oxidation flow through an external circuit (e.g., a wire connected to a device) to the cathode, powering the device.
Energy Storage and Depletion: The chemical reaction's energy pushes electrons from the negative terminal (anode) to the positive terminal (cathode). The battery depletes when the materials are used up and the chemical reactions cease.
Proper Disposal: Used batteries need to be disposed of properly.
