For living beings, carbohydrates provide an unparalleled source of energy. Now, that same energy can be used to power electronics. Professor Percival Zhang of Virginia Tech University has developed a battery that runs on carbohydrates. Zhang and his colleagues have developed an enzyme pathway which can produce up to 24 electrons per glucose molecule. The battery uses maltodextrin, a carbohydrate often found in processed foods. While the battery is still in prototype stages, if the technology becomes viable, this could become a more environmentally-friendly way to power smart phones and small devices.
