Part 2. How do circle batteries work?
Understanding the inner workings of circle batteries is key to comprehending their functionality. A typical circle battery consists of two main components: a cathode (positive terminal) and an anode (negative terminal). These components are separated by an electrolyte. The cathode is typically made of a metal oxide, while the anode is composed of a carbon-based material. When the battery is connected to a circuit, a chemical reaction takes place within the battery, resulting in a flow of electrons from the anode to the cathode. This electron flow generates an electric current that can be utilized to power electronic devices.
