Batteries are used daily and they are found everywhere from cars to all sorts of electronics and devices. If you think about it, battery usage is pretty heavy in the modern day because they are typically used everyday, and everywhere. Knowing the importance of energy storage in batteries and its high usage, it is important to know how these batteries work. A battery contains stored energy within the cells in the battery. A battery contains important components called the anode which is an electrolyte and the cathode which is the metal. Visually this can be seen as the positive and negative terminals of the battery. When these terminals are connected in a circuit, electricity is produced. The circuit connecting the terminals allows the circulation of electrons and the cathode and the anode to react with each other in a chemical process where the metal reacts with the electrolytes creating heat and hydrogen gas which is the energy that flows through the circuit. Different elements of anodes and cathodes can be used to create different types of batteries, where the reaction between the two determines the amount of energy produced by a battery. Batteries power lots of devices, so it's interesting to know that the batteries powering your electronic devices work through a reaction between natural elements.
