Approaching the theoretical density limit of ultrahigh-nickel cathodes via cation-disorder-free 10-μm single-crystalline particles - Nature Energy
Single-crystalline layered oxides can reduce capacity decay in nickel-rich cathodes, but controlling both the particle size and cation disorder is challenging. This work reports cation-disorder-free ~10-μm single-crystalline cathodes that deliver high volumetric capacity and cycle stability as well as improved safety.
