Can sea water into a source of energy which is better? This time we got the best battery is lithium-ion. These batteries store more energy in a smaller and lighter package. But the battery in a variety of electronic devices has some drawbacks. The materials used to make these batteries is not very abundant in nature so that they tend to be expensive. These batteries are also still vulnerable to fire and have a shelf-life is not long. Therefore, Professor Youngsik Kim and engineers at Ulsan National Institute of Science and Technology, South Korea developed a seawater battery. As the name implies, these batteries use water and salt as a source of power. Sodium is very abundant in the earth so that the battery will be much cheaper and reduce the possibility of burning incident. Researchers believe in the future of seawater could become a major energy storage. Moreover, because the world needs to switch on renewable energy. This energy can then be used as a backup for residen
