Abstract

Compositions and methods of preparing energy storage device electrode active materials and electrodes are described. A two-step synthesis process may be utilized to prepare single crystal electrode active materials and electrodes, such as a single crystal nickel-cobalt-aluminum material. In some embodiments, the two step synthesis process includes a first and a second lithiation step.
