Stable cycling with a high energy density at an affordable cost is a key challenge for the prevailing cathode material, Ni-rich layered oxides, to power the development of long-range electric vehicles. Now, Sun and co-workers introduced a Li[Ni_0.90Co_0.09Ta_0.01]O₂ cathode in Nature Energy, demonstrating great potential to overcome this challenge.
