DO NOT EXPOSE LITHIUM ION BATTERIES TO WATER OR FLAMES.*** | | All batteries have a lifespan. For example, when a phone's battery capacity is below 80%, the phone's battery life will become very short. It’s necessary to replace the new battery with a new one. For old batteries, simply throwing them away is a waste and can pollute the environment. Batteries are made from a number of materials including acid, lead, nickel, lithium, cadmium, alkaline, mercury, and nickel-metal hydride. When battery disposal is not handled correctly, the battery can leak, potentially contaminating the soil and water, and possibly harming human health. Therefore, REWA will share a way to convert old phone batteries into a power bank, turning trash into treasure. | | | Terminology: Anode = Positive terminal, Cathode = Negative terminal |
