Prep: 30-40 Seconds
Scientists have improved promising battery technology, creating a single crystal, nickel rich cathode that is harder and more efficient than before. It's one step toward improved lithium ion batteries that are common in electric vehicles today. Increasing nickel content in the cathode is on the drawing board of lithium ion battery makers largely because of its relatively low cost, wide availability, and low toxicity compared to other key battery's materials, such as cobalt.
