While nickel holds great promise, in high amounts it can pose problems in batteries. "But large-scale deployment has been a challenge." "Nickel-rich cathode materials have real potential to store more energy," said Jie Xiao, corresponding author of the paper and group leader of PNNL's battery research program. Nickel 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 materials, such as cobalt.
Scientists are working on ways to store more energy in the cathode materials by increasing nickel content. The promise of a nickel-rich cathode: More energy capacity Constant chemical reactions take their toll, limiting how long a battery lasts and influencing its size, cost and other factors. A battery's simple appearance belies its complexity, and controlling the complex molecular interactions within is essential for the device to operate properly. Improved lithium-ion batteries are critical for broader adoption of electric vehicles. Researchers around the globe are working to create batteries that deliver more energy, last longer and are less expensive to produce. The team's work on the cathode, one critical component in the lithium-ion batteries that are common in electric vehicles today, appears in the Dec.
Singlecrystal drawing how to#
Department of Energy's Pacific Northwest National Laboratory report new findings about how to make a single-crystal, nickel-rich cathode hardier and more efficient.
