Let’s embark on a journey to understand the science behind batteries and their transformative role in our daily lives.
Battery Fundamentals: The Building Blocks of Energy Storage
Cathode: The Positive Electrode
The cathode is the positive electrode in a battery, responsible for providing the ions that flow through the electrolyte during discharge. It’s typically made of materials like lithium-cobalt oxide or lithium-nickel-manganese-cobalt oxide.
Anode: The Negative Electrode
The anode, the negative electrode, is where the electrons are stored. During discharge, electrons flow from the anode to the cathode, creating an electrical current. Common anode materials include graphite or lithium metal.
Electrolyte: The Conductor
The electrolyte is the substance that allows ions to move between the electrodes. It’s typically a liquid or gel that contains dissolved salts or acids. The electrolyte completes the circuit and enables the flow of ions.
