Abstract

Abstract : A high‐energy nickel‐rich cathode with primary particle concentration gradient is developed via a simple, one‐step process involving a sacrificial polymeric‐bead cluster. The primary particles' gradients and internal buffer space in the secondary particles are successfully formed without any surface coating reagents. It is demonstrated that the cathode material has a high specific capacity and thermal stability.
