        Search for the Super Battery | Designing a Cheaper, Safer, and Cleaner Storage Battery

        Examine a new approach to create a cheaper, safer, and environmentally friendly battery to meet society’s energy-storage needs, in this video from NOVA: Search for the Super Battery. Battery scientist Jay Whitacre explains how he developed a functional “saltwater battery” as an alternative to lithium-ion (Li-ion) batteries. A key aspect of his battery-design process was to identify elements abundant in Earth’s crust in order to reduce material costs and the environmental impact of mining. While Whitacre’s battery produces less voltage than a Li-ion battery, it requires fewer factory controls, is nonflammable and nontoxic, and is already used in hundreds of solar installations around the world.
